Nice!

Exceptional value these are but repair costs can be huge.

How did you feel going from a 2015 to a 2005?

Im looking at 07/08 997s but concerned about going back agewise by quite a few years. Currently in an F12 640d which I’ve had for over a year now and to be fair its been brilliant but i always itch for a new car after a year or so.....
Repair costs could be lively granted but i'm getting the BMW all cover warranty so that will offer some peace of mind.

In all honesty for driving i'm all about the experience and not necessarily the luxury. The C63 was lovely and had all the toys but, aside from keyless entry and start, the M has everything the C63 has and more if you count the HUD.
The gearboxes aren't really comparable. I actually hated shifting the C63 paddles myself as it felt so soulless as the shift just happened and the engine note blended into the next rev range. I did enjoy the downshift pops in sport plus mode though and unless the M6 has some popping etc on the overrun I'll miss that even though i know it was a little feature contrived by the AMG techs. I am aware that fitting the catless headers on the M6 has the same effect but the £3k price tag to do so doesn't really fit my scope for this car.

It is also worth bearing in mind that I put 10k miles on my Vanquish which is a remarkably similar car to the M6. It was a couple of years newer but the the M6 actually feels a newer car, particularly with the spec it has.

So to sum up, materially and interior design I can see and feel the difference between the M6 and the C63 but in terms of build quality the M6 is head and shoulders above the C63. The Merc was a creaky rattly thing when I bought it new. It went back a few times and was eventually sorted. The M6 however feels utterly solid and not rattle to be heard. There is the slightest squeak from the drivers seat base which i'll look at this weekend before my run on Sunday.

I'm also based near Aberdeen, if you're looking for a good garage to look after the M6 Scott Feaks at Premier motors on the hardgate is very good. He's been looking after my 2005 645 for the last few years and I won't take it anywhere else now.
(just noticed that you're going to be extending the warranty, main dealers only then!)

Car looks great, how do you find the SMG gearbox?
I know of Scott and have suggested to my mother than she takes her Z4M there on a few occasions.
I have used AW Autotech with great success too over the years and Kev there is ex-BMW and knows these cars well.

The BMW warranty will mean maindealers for servicing but unless a warranty issue i'll be going the indy route if i can't do it myself on my garage ramps.

As mentioned previously I haven't really had the chance to fully appreciate the SMG box but will do this weekend.
I can say that the auto mode is much better than the Vanquish but still incomparable to a true auto. Driven with some thought it's perfectly useable however.
The paddle mode is good, slow shifts at lower speeds and faster shifts at higher speeds. Will see how it compares at the weekend on a longer drive.

An amazing car, and I still miss mine. frown
I’d leave the exhaust alone, though the factory system isn’t overly strident, it’s louder than you think outside, and sufficiently muted on the inside to make the car relaxing to drive, and when you’re really on it, the V10 still makes it’s presence felt aurally.
Don’t be tempted to fit aftermarket lowering springs, the factory knew exactly what they were doing when they designed and specced the spring and damper rates.
It’s shame they didn’t rethink the fuel supply needs however... If I bought another example, I’d engineer some additional fuel capacity into the boot (another 5 gallons should do it).

I’d also address the poor brakes with a front BBK from AP.

Comments about the interior spot on, the Merc interior build quality is atrocious in comparison, but let us not forget, this was the best BMW could do in 2005, their technical tour de force, and it shows in the quality of the interior (sure it’s looking a bit dated) but the way it’s screwed together, and the quality of materials used, is peerless. Driven sensibly and on standard suspension, the interiors remain completely squeak and rattle free.

Gearbox not the best around town, I learnt to use the paddles at all times, rather than rely on the ponderous and often jerky up and downshifts provided in Auto mode.
On the plus side, the SMG ‘box in “max attack mode” when really hooning, was superb, analogue enough to make things interesting for the driver, quick enough to make the car fun to drive, and it provides wonderful (and accurate) blips on the downchanges. No crackles and pops, but the sonorous sound of the V10 more than compensates for that shortcoming IMO.

As you’ve said, most see the headline figure of 500hp and rear wheel drive and think “Widowmaker” or lethal in the wet. The reality is so different, the V10 isn’t massively torque laden low down, and it’s linear power delivery makes it sooo easy to meter it out even in damp/wet conditions.

Out of ALL the performance cars I’ve owned :

Mk1 Escort Mexico (1st car)
Chevette HS
Opel Ascona 400
E30 M3 Evo 2
Sapphire Cosworth 2WD
VR6 Golf Highline (a massive brain fart)
E36 M3 Saloon
Impreza 22B One of 16 UK cars
964 RS Midnight Blue
964 RS Guards Red
993 RS Guards Red
Impreza P1
Mk1 996 GT3 Zanzibar
964 RS Rubystone
996 GT2 Midnight Blue
Gen 1997 GT3 Meteor Grey
Subaru Impreza WRC car (the 2nd WRC car Prodrive built)
Mk1 996 GT3 Zanzibar (I bought it back ! !)
M3 CSL
996 GT2 Basalt Black (Ohlins, remap, Ruf exhaust)
996 GT3 RS White with Red
Gen 1 997 GT3 Slate Grey
1M Coupe Orange
1M Coupe White AP's, Sparco race seats install, decat, custom geo set up.

The M6 was the best. Not the fastest, not the best braked, not the grippiest, not the most focused, but as an all round hugely quick package that could be used in all weathers, it was utterly peerless.

Warranty a must have, a decent dealer with a technician who understands the cars, the same.

I WILL have another ! !

Slippydiff,

Wow, that's some write up and certainly an accolade for the car to be considered better than what can only be described as most people's lottery list of cars!

I won't be changing the exhaust. I heard it all properly last night and am perfectly happy that its the right blend of quiet and loud at the right times.

I also wouldn't change the suspension either as it was something I noted as being so good from the first time I drove the M6. I'm going to get mine on a Hunter machine to check the geometry just to be sure its all correctly aligned but it feels good.

I can see the fuel issue looming. I've done 20 miles of town driving with a few spirited accelerations and have used just under a 1/4 tank. I will find out this weekend what the car's true endurance on a run is but would imagine i'll not be passing the Shell station too often without popping in!

I'm interested to see how the brakes perform. It hasn't felt underbraked so far but maybe they overheat and suffer fade longer into a drive. I'm not against fitting a bbk to the front anyway but would have the calipers in black to match the car as it stands today.

I find the top 1/4 of the tank isn’t really representative, it seems to disappear between 20 & 35 miles regardless of what you do. 2/4 can however be at 65 - 150 (town/run) as my two outliers so far. Always v-power too.

I’ve done a true mileage/fill table for mine in my RR thread, and will continue to do so.

Basically, I’m getting 10 around town, 20 on the motorway.

To be honest that's not hugely worse than the 645, and you have an additional 170bhp to play with!
I notice that on mine the gauge starts moving pretty much straight away, there's no period where it stays on full like other cars.

Nice as it is, forget the M6 and tell us more about the Aston and the Alfa hiding in the garage.

Cheers for the heads up, I'll be refilling before sunday (although the forecast appears to suggest it'll be -3c on Sunday morning so i'm not sure how many of my buddies will be up for digging out the exotics for a drive) so will see how quickly each section drains!

Simple really;

Aston is a 1969 DB6 Volante Mk1. Painted in Caribbean Pearl and with blue itnerior and hood. It has been in my family since new and has covered around 45k miles iirc. It is in completely unrestored condition.

The Alfa is a 1968 GT Junior that I imported from NZ a few years ago to race. It's a fully prepped 2ltr car eligible for any club level classic racing. Huge amounts of fun are derived from getting it out. Oh and it's road legal which is nice.

Got the M6 out for a reasonable drive yesterday and it's fair to say that i'm even more impressed.

It was -4C when i started the car yesterday and the day never warmed at all but it was sunny and fundamentally dry.

I headed out with some friends in their various exotics (Lambo Performante, 991 GTS, 991 C4S & AM V8 Vantage) so it would be fair to say the that the budget Bahnstormer was in some fine, if somewhat better heeled, company. Undaunted, the M6 (with M button pushed of course) set off in convoy as we headed for the breakfast stop. Whilst very cold there was still some grip and we were able to make good progress. It was the first time I had taken the car above even 6k rpm and i'm delighted i have now! It makes a lovely sound. As mentioned in the thread earlier there is enough engine noise in the cabin to be pleasurable but not intrusive and the exhaust is audible but as background only. Perfect, I would say, for a proper GT car.

Performance:
The car has plenty of power. It's really controllable though as the delivery is so linear, no big lumps of power to spin the wheels. It pulls hard to the limiter and is extremely responsive when getting back on the power through a corner. To compare none of the cars present had the legs on the M6 in the driving conditions we had that day. A great engine!

Gearbox:
The box really did come into it's own on the open road. Its perfectly quick and I was up and down the gears exactly as I would be in any of the other cars I have/have had. I also really like the fact it too will skip a downshift gear by double or triple tapping on the downshift paddle. Genuinely I can't say anything bad about it. It's a very good system!

Handling:
I given the nature of Scottish B-roads in the winter I should have raised the suspension and stuck on a set of knobblies but in the absence of those the 'comfort' ride selection was chosen. Its a very well damped car with absolutely no lack of compliance over even the most rutted of corners. I did firm it up a couple of times to the 'normal' setting and once to 'sport' but the latter was far too hard and I found sport to be nice enough but still slightly jittery on the more damaged/worn sections of road. I did feel that the front wandered a little under power though and the rear was waggling all over the road. The tyres are certainly long past their best and will be changed asap. I am also going to get a full geo setup to check everything is pointing where it should be.

Brakes:
I found the brakes fair enough. They have sufficient initial bite to feel good but there is a slight lack of ultimate stopping power from speed. I didn't really get them hot enough to fade but got the impression that I probably could without too much issue. I wanted to retain the originality of the car but this may be something I improve by way of a caliper change and disc size increase. I want to keep to the 19's though so nothing that will compromise that.
I see that there's a set of M Performance calipers and discs on eBay at the moment. They're quite scabby so easily repainted black as I would need and the discs are scrap as they have cracks propagating from the drilled holes in the disc face. Seller says they "just about fit under the 19's but would recommend 20's" so i'll ask him what he means by just about.

Never used to be sure of the looks but it has aged well. Interior still looks fresh, better than the M5 of that era IMO. The engineer in me drools over that engine though, absolute masterpiece.

Glad to hear you’ve done a proper stint behind the wheel James smile
They are very addictive cars. In the oh so short time I owned mine, nothing came past me on fast A/B roads, this was down to two things, the sheer confidence the car instills, and the car’s intrinsic balance. With the TC slackened off, the car is really run to drive in the wet, but it’s also soooo controllable.

The fact you can enjoy such crushing performance from the comfort of an interior that feels and looks closer to that of a gentleman’s Club than a 500hp supercar, only added to the slightly surreal nature of the car.

I suspect the front pads and discs were past their best on my car, so fade was easily attainable (but quite frankly even in rude health the OE brakes were hopelessly under-specced for a 500hp 1800kg car) I’ve no doubt the AP 6 pot/ 378mm front brake upgrade would rectify the problem in one fell swoop.

The gearbox suits the car perfectly (as does the SMG ‘box in the CSL) and also works remarkably well with the magnificent V10, and once familiarised, becomes totally intuitive, so much so I’m not sure I’d want a manual even if such a car had been available here in the UK.

A new set of tyres and geo will transform the car further still.

Very, very nice, well done. I had the M6 on my shortlist but ultimately chose the XKR instead - I may end up with one of these yet though. I'll look out for you in Aberdeen.

Well the small fuel tank in this car could well be an issue. That was 118miles between fills and i left it until it said there was 32 miles left in the tank. The car took 56litres so there was still 9 litres in there.

I'll see how my real use works with the tank size as this week hasn't been typical.

In other news the A/C re-gas has done the trick as we are now icy cold in the car.

The Dent Devils man is an hour away from me now so hopefully he can improve the dent in the rear arch. He'll be getting a massive pat on the back if so as it's a tough one!

The drivers seat has developed a creak so i'll do some investigating this weekend. I suspect it's from the plastic casing that covers the motors and mechanisms operating the seat. Should hopefully respond well to a suitably placed felt sticker.

Otherwise the car is just superb. Really enjoying it and am completely at home with it. I actually find the auto mode fine and run to and from the office entirely in auto. I do put the shift speed up to 4 out of 5 as that seems to force the box to downshift to 1st gear when i stop. If i leave it in 1 or 2 of the 5 settings then it seems to choose 2nd gear for pulling away which i feel must run the clutch for longer.

There is indeed - Click here.

On topic - Beautiful car, I remember when they first came out I wasn't a fan of it's looks, felt it was a bit too lumpy but over time that opinion has reversed. Now I see them as purposeful, brutish but also elegant in their own way. Enjoyed your write ups so far and look forward to more updates on the car in future.

Scott looks after my e60 M5 servicing, I've not had any issues with any claims on my BMW approved extended warranty. Had a broken spring covered and a traction / ABS / control module fault, A 2.5k bill if I recall, All covered under warranty,

Servicing by scott is a must.

I ran an E60 M5 V10 for 4 years without any trouble but it did have Mondial warranty. Took it on holiday 4 up through France and averaged 21mpg over about 2000 miles. I think the tank needed filling ( down to a quarter ) after about 230 or so miles each time. Running about at home was more like 170-180 miles. Did a trackday at Bedford and the SMG was great.
Re exhaust, I had mine modded and within a few months put it back to standard as couldn’t stand the noise. One thing I did which was well worth it was load one of Jim Colleys ( Fast attack motorsports from the US ) maps onto the car, made the car even smoother and SMG even smoother plus more low down torque. The way the engine delivered the power and just kept revving it was relentless and the sound!
