Evening all, I’m p/ex’ing my Merc 500 SL for a 4.3 Griff next week and need refreshing on what to look for when viewing. It has been years since I owned a 4.3 and whilst this car looks in great condition and has a great history file, what should I be looking out for, outside of the obvious of checking underneath - which I have already seen close up picture of, any obvious engine issues and electrical problems. Are there straight forward checks for leaks vibrations fuel issues (i.e throttle response - that typically affect the running cruising of them ? Anything I have missed ?

All help really appreciated.

4.3 is the best of the bunch imho, having had 7 tvrs with rv8 engines. Engine should rev freely and worth checking engine number does have 43 in it somewhere. You haven't mentioned mileage but most rv8 really need to have cam replaced at around 50k to 60k to maintain performance, so check history for that.
I would check coolant level before starting as probably will not have expansion tank and once started check fans kick in at around 90 and then switch off when cooled slightly. 0il pressure readings not that accurate but as long as steady it should be fine.
Otherwise check chassis carefully. Most will need to have outriggers done at some point, so if already done so much the better.
Things are fixable so it depends on what you are prepared to do or have done. It is cheaper to pay more initially for a good one than buy one cheap that needs lots doing.

Miles are just 70k, from what I understand it has had a top end rebuild, but naturally will check receipts. It also had a diff replacement. It has been fitted with a Mallory ignition ? The car has been waxoyld every year and chassis/outriggers look in great condition.

Chassis and outriggers. If it's not already been done then more than likely it will need doing during your ownership.

Here is what to look for:

If you need to budget for riggers and don't want to do it yourself, then just as a guide Central TVR, which is too far from you in London, would cost you £1,800.00 plus VAT.

As I say chaps, chassis been waxoyld every year and all looks really good underneath from pictures I’ve seen and reassurance from guy selling it. It’s more about any other obvious things to check.

Some good advice though chaps, please keep em coming as it all helps. As I say been long time since Griff ownership

Yes,I recently purchased 4.3 92 vintage, if manifolds are original with y piece mine are and need replacing wafer thin on y piece, 2 k plus. For Clive ford manifolds or £1,300 for standard. I'm saving hard

Chassis.
Electrics- check the heater fan as it’s a PITA to fix.
The electric windows are slow.
Alarm remote works ok?
Boot mechanism works ok? Cheap to fix but a PITA if you get to a garage low on fuel & can’t get into the boot.
Chassis
The 4.3L is a very revvy engine, make sure it does (when warm!).
Leave it idling & make sure the fans cut in & watch the temperature readout. Pre-cats can run a little warmer than the later 5L.
Has it got an alloy rad? If not, is the original in good condition.
When hot check the idle oil pressure. It’s a good sign of how good the oil pump is.
Chassis.
Brakes- has it got the original 240mm front discs? These are rubbish IMHO a common fix is to fit the later 260mm 5L discs.
LT77 box is a bit marmite, I personally like it as 2nd is a bit higher than the T5. A loose change can be fixed with replacing the nylon bearing at the bottom of the lever.
What suspension is it on? The original is 27 years old & there are plenty of better choices around now.
What wheels is it on? Should be either cross spokes or 5 spokes (with the centres as these are rare & irreplaceable).
What are the tyres like? Griffs are light & torquey, decent tyres make a huge difference.
Widescreen surrounds can be poorly fitted- takes a bit of fiddling to get it to look right if its been bodged.
Widescreens were in short supply- look at the corners for de-lam or milkyness.
Chassis.

Way back in the dark old days, the general consensus was that if a car has had a top end rebuild - that would then put extra strain on the bottom end causing problems. Why did it need a top end rebuild?

The electric windows are slow. (He said windows slow)
Alarm remote works ok? (Yes apparently)
Boot mechanism works ok? Cheap to fix but a PITA if you get to a garage low on fuel & can’t get into the boot. (He confirmed working fine)
Chassis (looks ok in pics)
The 4.3L is a very revvy engine, make sure it does (when warm!). (Will check)
Leave it idling & make sure the fans cut in & watch the temperature readout. Pre-cats can run a little warmer than the later 5L. (As above)
Has it got an alloy rad? If not, is the original in good condition. (Will check rad and ask if ever replaced)
When hot check the idle oil pressure. It’s a good sign of how good the oil pump is. (Will do, but worry how accurate gauges are)
Chassis. (laugh Looks all good)
Brakes- has it got the original 240mm front discs? (Upgrades brakes, but will check if discs lipped) These are rubbish IMHO a common fix is to fit the later 260mm 5L discs.
LT77 box is a bit marmite, I personally like it as 2nd is a bit higher than the T5. A loose change can be fixed with replacing the nylon bearing at the bottom of the lever. (He said gearbox nice and smooth, will check)
What suspension is it on? The original is 27 years old & there are plenty of better choices around now. (Upgraded suspension with ride height adjustment, will check for shocker leaks)
What wheels is it on? Should be either cross spokes or 5 spokes (with the centres as these are rare & irreplaceable). Original 5 spikes which I love)
What are the tyres like? Griffs are light & torquey, decent tyres make a huge difference. (On Toyos but admits they are getting low)
Widescreen surrounds can be poorly fitted- takes a bit of fiddling to get it to look right if its been bodged. (Will check)
Widescreens were in short supply- look at the corners for de-lam or milkyness. (Looks ok in pics, will double check)
Chassis. (As above think ok )
Thank you

Will ask. Previous owner 17 years, so will see if he knows.

I too reckon the 4.3 is the best option (having driven all alternatives) - This was endorsed by John Eales, RV8/ TVR engine guru from purely an engine standpoint.

I found the 5.0 a bit like cracking a walnut with a sledge hammer - alarming on greasy roundabouts with such a slug of low down torque.

The 'vocals' are simply the main reason and clincher - It has to be pre-cat to benefit from the full 'HDR' depth of character and the 4.3 is both free revving and quick enough (0-60 near 4 secs)- The 5.0 lacks the warmth and charm in exhaust note - for some reason, even when de-cat IMHO

My perfect choice would be a 4.3 with a mildly more sporty cam, ITBs (mildly silenced) and an auxiliary tuned melodious switchable main silencer to quieten the cruise for long journeys (an age thing..)

Suspension was under developed and would benefit from having dampers and springs set to your taste (dont lower it!)

Not sure what current values are, however I believe at some stage in the future investors will favour the 4.3 over other models and values will climb to £25k before long

Relatively easy car to drive providing you Always respect the torque / weight ratio under your right foot and never rely on heavy braking to get you out of trouble - not very effective and can favour the rear when the back of the car leaps 3 inches upward - applying evasive steering at the same time will launch an educating 'fish-tail' ...at best..

The looks are legendary, the sound is awesome, lovely kevlar targa panel, absolute simplicity of design throughout - sensibly valued...for the time being

Thankyou Peter + TVR team for your amazing achievements...we miss you

I completely agree with you. I have had 2 Griffs, a 4.3 back in 93 and then a year later 1 of the very early 500’s which I got to say, I was disappointed with from the start. It didn’t sound anywhere near as good as the 4.3 and even after cutting out the silencers (seemed a good idea at the time) it still wasn’t as good....noisey ! but just not that great note we have grown to love on a pre-cat Griff.....Plus it handled very poorly at speed , with the front end becoming light and vague. I spoke to Neil Anderson about it several times & when I look back, it’s quite comical having discussions about me fitting an aluminium style diffuser to help keep it planted. Neil said they were open to any kind of attempts that might help. I think in the end and on 94 MY cars, they fitted a strengthening bar to the section behind the front number plate, but am not 100% certain ? and thought that only stopped a vibration that was occurring at high speed ?

I took both of my Griffs on several track days, many where Peter Wheeler, John Ravenscroft and Neil Anderson we’re in attendance, running developments on cars. I loved those days and got to know them reasonably well over the 4 years I had ownership.

I’m really looking forward to getting back into a Griff and hope the car I’m getting is as good as it appears to be (and been told) so that I can get some immediate hassle free miles under my belt.

Hi Duc, good to hear your comments smile - I too attended several track days and joined Peter and the development team in the pits for a chat smile

I made my observation to Peter that at the end of the pits straight, when the Griffs braked to take the right curve, the back bucked into the air, unweighted and at best unsettled rear end grip - realistically entering a spin that wasnt easy to catch..

Peter looked at me, gave me one of his laconic smiles, paused, then said ... 'mmm, yes they do that, dont they..'

Having recovered from his typical frankness, I turned to Neil or John and suggested a pulley + cable / or hydraulic solution that would keep the tail planted when the front dived under braking..another pause, they looked at each other, then said 'yeah we do that on the race Tuscans!'

I also remember chatting to Peter earlier in 1990 at the Griff Earls Court launch - like so many others, I was smitten with the clean beauty of the car. Deposits were pouring in, based on this prototype built on the S chassis.

As we got to know each other a little, he took me to one side and said 'You will never get the chance again to buy one at this price new' - so right he was - 5 yrs later I paid more second hand privately....the rest, as they say, is history..

I believe I am right in saying the Griff and Chimp were 'designed' by Peter on the back of his cigarette packets and then handed to the team to evolve - The Chimp buck was savaged by Ned around the front indicators, giving rise to that sort of bitten out scoop

No doubt you already know, but the rear transom at front of boot is usually signed graffiti style during production

Many stories...Gerry Marshall the legendary saloon car driver had a Griff and became a regular customer of mind - I used to train under him at Brands too, many yrs before - drove him to the local for lunch once or twice in a Scimitar GTE (which I still have) ...I remember him asking me to slow down (on a straight country rd)...I was surprised but never questioned why, simply obeyed - turns out he was very ill at the time so I imagine it was discomfort from the bumps ...,

Where am I going with this..oh yes, another time he promised to drive me around Silverstone power sliding a Griff all the way....I met up with him and Peter there, however I chickened out as I was suffering from heart rhythm issues - as the Boss and I returned to the back of the pits, our conversation was punctuated every few seconds by long tortured lurid screams of rubber as Gerry enjoyed drifting the Griff through the corners - we looked at each other...'Gerry!'

I also had the privilege to talk to Trevor for a good while at the factory and dinner with Ben and his fiance - would be nice to do the same with Elon and his development heads..

I loved the factory tours which reminded me so much of shoe factories I knew from my youth, spread as it was across many ramshackle old buildings - the casual presentation by Ben, Ian and Neil - the wonderful aroma of resin and leather - the mind boggling amount of body prep that was required....

When we crossed the yard from one building to another, we passed a stack of chassis left out in the elements - I commented that werent they concerned about rust -- nah, the steel is too thick and well protected.......hmmmm - galvanise them next time boys smile

Good times..

Due to health and ensuing lack of finances, my beloved Griff languishes in the barn for more years than I care to think about....most days she is not far from my mind and cannot wait to drive again..............

Great stories smile

This will never happen again in our life time, where you can have a good chat with the owner and designers of a car at a track day or in the factory, that is not beyond the reach of most peoples pockets. Some pay millions for that kind of 1-1 approach and whilst they prob achieve great quality with a Koenigsegg or Pagani or other similar cars, I still don’t think they have achieved any better than the great simple design of the Griff.
