Well, my January 1998 E39 535i has reached the point that it needs some TLC. The old girl is 21 and a half years old and owes me nothing, and with the MoT up next week, I need another car. The other V8 E39 (a 2001 540i Touring) is currently fked after the header tank let go at 70mph on the A303, and, along with the 520i Touring, is currently two hundred miles away from me, up in Surrey. I'm just the Devon side of the Tamar at the moment. I randomly spotted this 760Li on eBay a couple of weeks ago, and although I wasn't brave or stupid enough enough to go for it, my elder son had other ideas... and my eBay password. Well, the 535i was an unseen eBay buy too, so how bad could this be? Seven thousand imperial credits of the realm and a fee to get it trucked down from Middlesbrough to Plymouth later, here it is...






It actually did the first 200k in just three years! There is a very slight misfire at idle when cold, and cosmetically it's not wonderful (and the paint is full of orange peel), but it drives magnificently, as tight as a drum...

It's also had most of the big scary jobs done - coolant return pipe replaced, new ABS module, the gearbox has had a load of work done, new spark plugs, new lower front suspension arms, new coolant header tank, etc etc. Giving it about one third throttle on the A388, it leapt forward with alarming urgency. I haven't had the balls to get anywhere near full throttle yet.

The mileage history is as follows: 201,003 miles at its first MoT in November 2008... which it failed on leaking rear air suspension units. It then did 2,511 miles with no MoT until it failed again on the same items a couple of weeks later, and finally passed the following day. Then only 7,773 miles to the 2009 MoT, 5,350 up to July 2011 (must have been off the road for much of 2010), then only 2,935 miles to March 2014, 4,782 miles to June 2015, then 14,729 in the following year, then 6,903 in 14 months or so to August 2017, 10,867 miles in August 2018, and just 3,088 miles in the ten months since. It hadn't been taxed since February until I taxed it a few minutes ago, which might explain the misfire. Certainly, the seller (who only acquired it a few months ago) fitted a new battery before it came south on the back of a lowloader.

Onyx Blue indeed... and no, simply that trucking it was cheaper and a lot easier for me than trekking all the way up to Middlesbrough by train!

Well, it's been to Great Torrington via Okehampton and back this evening, and I am *not* going to admit what the lepton count was on the straights around Hatherleigh... but it also got hammered like a sports car in the tight twisty bits. I am seriously impressed at how good it is.

At some point I could do with meeting a fellow 760Li owner to learn everything the car actually does and identify the causes of the few minor issues it has, like the intermittent lighting of the inner quadrants of the dials, and the slight misfire at idle...

Is 7k a bit steep? Maybe, but that's market forces, it was an eBay auction and I wasn't the only bidder by any means. I actually won it at £7750, but the seller insisted on knocking it down because of that rough idle. I'll need to get the plug and coil checked, but it is so smooth at higher RPM, and it had new plugs last autumn... hmm.

Autotrader has 10 BMW 760li. 2 below £10,000, the next one £20,995. Strange?
Fantastic car but £7k seems an awful lot of money, just found one on Autotrader, 2006/56 with 71k for £8500.
I'm wary of low-miles cars after my experience with the E39 520i Touring... I bought it at eight years old and 54,000 miles. It proved a total moneypit until the engine finally died and was replaced with a higher-miles one, since which time it has run flawlessly. I would rather know that the car has been run in properly, has been well used and maintained accordingly. Besides, I quite like the idea of having the highest-mileage 760 in the country (I presume!). I will certainly be taking it past 300,000 (assuming it doesn't go pop before then) and hopefully well beyond. Who knows, maybe my sons will end up taking it past a million. There is definitely a sense of permanence about this car - it feels rock solid in terms of build (apart from the broken seat-back map pockets, but that's a very minor niggle).

Also, that £8500 Autotrader 760 is grey inside and out - not for me. Very dull. Much prefer my one's colour scheme. That said, it and that cheap 2003 one have a few options missing from mine - there is no fridge or rear iDrive in mine, nor air vents in the headlining (though it does have them on the B-pillar). I wonder if it would be possible to get any of those items retrofitted?

I like that, but I would have thought half that money, if that, at that mileage ?
Like I said, it was an eBay auction and other people wanted the car too. It had already reached £5100 before I started bidding in the last ten minutes, and there was a minor bidding war to the end, which drove it up to £7750. The seller kindly gave me a £700 discount due to the idle misfire. Is 7k a bit much? Maybe, but that's market forces for you. Other bidders thought it was worth up to £7550, I had to beat that by £200 or lose the car.

Given his willingness to discount the car, giving me the opportunity to walk away from it (I refused), and fitting it with a new battery at no charge, I don't think so. Besides, if I'd dropped out, "his mates" would have been stuck with the bloody thing, unless it got relisted again... and I would have rung alarm bells at it being relisted multiple times over. Anyway, it's had the day off today, the weather is utterly foul here in the SW... pouring rain and gusting wind. Welcome to summer.

Valley pipe has been done quite recently (not at my expense, thank goodness!).

I wouldn't be surprised if someone else, like me, saw it when relisted and decided to bid on it. I wasn't bidding first time and I have to take my share of the responsibility for pushing the price up. As I said, the seller offered me a way out or a hefty discount when he discovered the misfire at idle and couldn't have been more helpful generally, so I really don't believe he was trying to push the price up. 7k is still a tiny fraction of the original value and the car has had that much and more spent on it in the last couple of years.

Did an 80-mile round trip on Monday, from near Launceston to Exeter and back, bit of winding country road, bit of traffic-jamming around Exeter, and miles of A30 in between... aside from that little misfire below 1000rpm or so, it didn't miss a beat all evening. I'd expected it to feel a little bit loose and tired at this mileage, but it just doesn't, not one bit. My nearest comparison would be with my 540i, which had 225k on it when the header tank blew - it was still very good to drive, but it did develop a few little rattles and clonks in the 10k I put on it. I still have that car, it's going to get fixed once the 535i is done and will then become my son's daily hack/crap-hauler, but I didn't have the luxury of time to get it back on the road before the 535i went in for (and inevitably failed) its MoT. Hence this.

Anyway, I've put about 200 miles on the big beast so far and reckon I've done alright. While I am by no means rich (even financially comfortable is a bit of a stretch), I've had other expenses in life recently that have cost me far more and have given me nothing back but a bitter aftertaste... if I paid a grand more for this car than might otherwise have been the case, well, frankly, it pales into insignificance in comparison.

Thanks, that would be useful. I've learned most of the M54 and M62 foibles, but this N73 and the level of tech it embodies is a whole 'nother level for me. I'm betting it's just a knackered O2 sensor or somesuch... kind of to be expected with a car this age. It was definitely running a wee bit rich at cold start on Monday, with a bit of a smell of unburnt petrol, which was totally gone by the time it was warmed up, and did not reoccur on either one of two restarts in Exeter - I'm guessing there was a fair bit of residual heat there, whereas on the first start it hadn't run in about 90 hours.

I had it parked right next to the west end of the cathedral (I'd popped in for Evensong while my younger son did a bit of shopping nearby), but the weather was so utterly miserable that there was no point trying to photograph it...

Oh, one other little thing - the wheel centre badges are starting to peel off, and the O/S rear one actually has come off (I retrieved it just before it fell off). Is there an easy fix for this? They're all a bit faded and yellowed too. A new set wouldn't go amiss, but I wouldn't want to have to buy new centre caps as the plastic is fine. A wheel refurb will also be on the cards at some point as the rims are pretty scuffed, and I need to get the bonnet stone chips sorted (they're down to bare metal), and there's the question of the peeling lacquer on the rear bumper where it adjoins both wheelarches... ah, but I'm relieved it isn't too pristine, I'd be paranoid about using it. Aside from that one wheel centre badge, it has yet to deteriorate in my custody, but my cars do have a habit of picking up scratches...

I was 27 when I bought my Mexico Brown 3500S TTS874M in 1984. Ran it as my daily for eight years until tinworm and lack of rear belts made me take it off the road. Stupidly stored it in a damp leaky lockup until 2008 when I eBayed it as a terminally rotten engine donor.

My other cars:

First car: my father's Humber Sceptre Mk2, ex-demo with a very high compression engine and hairy cam... refused to run properly on anything less than five star.

Then a Mk3 Cortina 1600E, also had some use of my father's 2-litre (which ended up becoming a parts donor for mine before I sold it)

Then a Mk2 Capri 1600E which got stolen and burnt out

Then the Rover

Got married, Mrs P6B then had a base model Peugeot 205 D96 PGO which I also drove. Glorious chassis with no power at all. It got traded in for a 1.4 Roland Garros with 72bhp - a bit peppier.

Then Mum died and I inherited the Volvo 340 she'd bought after Dad's demise ten years previously. I ragged the crap out of the little beige snotter, redlining it in every gear just to make progress, for about 18 months, until it sheared a half-shaft and I decided to get rid of it, sold it to my mechanic who fixed it and then foisted the bloody thing on a bell-ringing friend of mine...

It's been BMWs ever since. Replaced the Volvo with the E30 318i Touring G508EVP. Replaced the Roland Garros with the E46 318i Touring V188DPH - quarter of a ton heavier than the E30 but no more power and no more space. Total moneypit, got written off when hit from behind while static by a schoolteacher on her phone in a VW Polo. Should have learned my lesson. Replaced the E30 with the first of three E39s, all of which I and MrsP6B still have, and each of which has presented the odd eye-watering bill (the 520i 2.2 Touring is on its second engine, the 540i Touring [an SE auto but with Sport suspension, diff & high-stall torque converter] is about to be, and the 535i has had a gearbox rebuild), but otherwise cost us bugger all. At times we only had one car on the road, but we're now up to three (she has the 520i Touring and an E64 630Ci drophead) with a fourth (my 535i) due back in days, and the 540i (currently in MJF's yard in Surrey) as a medium-term project... and my solution to all of this is to buy another even more complex and expensive BMW for a tiny fraction of its original value? I must be mad.

How the feck? That’s over 500 miles every day for a year!

Looks comfy
I've been asking myself the same thing! 67,001 miles a year or getting on for 5600 miles a month, about 1290 miles a week on average, or north of 183 miles a day every day throughout those three years... I would love to have more history on this beast, and especially what it was up to then.

How do you sit down with balls that big?
Thanks, but it isn't balls so much as some insane man-maths, perverse logic and my sons going DO IT! DO IT! DO IT! ...and it wasn't actually me bidding on the car at the time, but my elder son, who had decided we needed the car regardless of my trepidatious protestations! At least the 540i I actually agreed to buy simply because (after haggling on price) it was cheaper than the gearbox rebuild on the 535i... but even then, only after a lot of persuasion, nagging and man-maths on my sons' part (particularly the elder one).

In fact, it was he who found all three of the E39s for me. The last conscious purchase decision I made myself was the E46, and that proved something of a disaster! Even then, elder son (then 10 years old) had some input, and was trying to drag his parents towards the E39 528i Tourings... but MrsP6B was then a committed small car person, wanted an R53 Mini Cooper instead, and the E46 was the compromise we had to agree...

Don't even make me think about it. I shudder to think how much dino juice it drank under its former owners.

At least your lads have good taste!
Well, I did try. Elder lad was rising 18 when we bought the 520i, and was instantly attracted by its unusual Oxford Green exterior/English Green interior... but then he had gone through a teenage phase of dressing in check shirts and tweed, attending Tridentine Rite Latin masses, and was the youngest-ever member of the Pugin Society... albeit by this time he was transitioning into a long-haired neo-hippie atheist metalhead with a penchant for pairing light pink shirts with darker pink trousers, and admitted to harbouring a desire to own a Magenta Triumph Stag - as he put it, "they're the only pink convertible a straight bloke can get away with being seen in". He also thought the 540i with its Slate/Stone Green colour scheme (I forget which is which) made an ideal partner to the 520i. I still sometimes wonder what's going on in his head. The younger lad is less concerned with aesthetics and more with baking bread and waving a bloody great sabre around...

Well, it did come from a Birmingham dealer originally, and the vast majority of its service history is with Sytner Birmingham, plus one each at the Sytners in Coventry and, oddly, Chigwell... so I suspect you're not far off the truth. Bashing up and down the M40 between Brum and Heathrow and/or central London every day. Possibly the best car in the world for doing so at the time - Phantom too expensive and conspicuous, S-class at that time was the aging W220, Phaeton/A8/Flying Spud W12 just not in the same league for refinement...

About that... it hasn't had an oil service in 40,000 miles. That does make me want to give both the seller and the bloke he bought it off a few months ago a slap... last owner but one spent a fortune on it last year, including a full rebuild of the mechatronic unit on the gearbox, but couldn't stretch to an oil service?

At the moment, RL are busy enough with my 535i (they've just presented me with a bill for £3624, which doesn't include bodywork!), and I need to be sure of having transport... is an oil service on this a quick enough job that it can be turned round inside a day? As long as I have it back for the evening to get back home and/or do the taxi driver bit for my younger son and his burgeoning collection of swords...

At any rate, idle misfire aside, it's running very nicely at the moment, had it up to a nice steady 120 at one point, felt rock solid.

One other thought - the V12 kicks out a monstrous amount of heat! Not that heat soak in the cabin is noticeable, but when opening the bonnet after a run, one is hit by a wall of thermal energy... would it be worth using a waterless coolant like Evans in this?

One thing that REALLY annoys me is the cheap tubular metal boot hinges... utter crap! I would love to change these for some proper cantilever hinges at some point, if possible... the E39 is a much cheaper car yet has by far the better-engineered boot hinges! Given that the E65 was up against the supreme expression of Ferdinand Piech's OCD, with its beautiful Campagnolo titanium boot hinges... now there's a thought. Wonder what a set of those would cost?

That information wasn't disclosed in the eBay listing. Too late, I'm stuck with the thing, and I am not getting rid of it any time soon. It's running so well that part of me wonders if there hasn't been a more recent service that just wasn't recorded in the history. I shall email the seller to ask...

Plugs were new last November IIRC.

Boot hinges? Partly it's just my OCD, but the curved tubes are crude and bulky. At least, unlike some modern cars, they don't intrude into the boot space (or, rather, constrict it by necessitating a boot liner to be shaped around them), but they're hardly the most space-efficient design.

E39 - a much more elegant solution:



Phaeton - the same thing but with German/Italian over-engineering turned up to 11:

261,544 miles now. Long overdue an oil service and still runs like crap at idle, but otherwise nothing to report, except that a few electronic gremlins which initially appeared seem to have cured themselves... MoT is up on 6th August and I'm hoping to get it in before then for a few jobs, but it's reliant on the 535i getting fixed before then - it still isn't quite finished, although I'm told it should be done this week. It still needs to get bodywork done but at this stage there isn't going to be time to do anything about it before the 7's MoT expires. I did see a very cheap E61 550i Touring up for sale here in Devon a few weeks ago, wonder if that's still available... mustn't do anything silly... I need to get the E39 540i Touring fixed next! E66 will need new tyres and that's going to be very expensive, unless anyone knows a good source?

One job I've decided to do is get the calipers painted, or maybe go over to a set of Brembos or similar? The standard ones look rubbish, although the braking action is effective enough. The rear calipers look far too small too. I'm thinking a set of big yellow calipers would suit the blue paint.

At the moment the liar box is saying I'm doing mid 17s, although I had it up to high 18s before I reset the trip computer. Is this normal? I mean, I knew it was going to be horrendously thirsty, but I'd hoped I might see low to mid 20s. I guess the misfire and general engine condition isn't helping and that a thorough service should liberate a few MPG (and BHP!).

OK, I guess I'm not running it that low, but on Tesco 99 octane, 99 quid all but brims the tank. I can usually get another 2 quid's worth into the filler neck, but that's about it. Besides, I often meet other petrolheads when refuelling.

When I was using my 535i on the same general usage patterns, it wasn't doing much better, averaging around 18-20...

Part of me does question the sanity of the whole endeavour with this car. I am not particularly well-off, I currently have no income other than a minimal pension, and am living on the meagre proceeds of a house sale while living in short-term rented accommodation while trying to sort out something more permanent. It cannot be called an especially prudent purchase... but I needed transport capable of the odd 80-mile round trip (today was 143 miles) and, with the 535i in dry dock, I had little other option. I try to comfort myself with the thought that 7k isn't very much money and that I'm more comfortable in this over those distances than I would be in anything else. Public transport isn't really an option in these parts, thanks to Dr Beeching... when Boris scraps the monumental folly that is HS2, reopening the Okehampton/Tavistock route (and the branch off to Launceston, Wadebridge and Padstow), preferably stocked with Bulleid Pacifics and Mk2/3 carriages rather than cast-off Pacers, should be a high priority for the redistribution of that funding... but I digress. The furthest east I venture these days is Exeter, and the railway map west of Exeter was all but obliterated, with the exception of the slow and clunky Barnstaple branch and the GWR main line to Plymouth, which is no use for anyone north of Dartmoor!
