It's different, makes a fantastic noise and is plenty quick enough.
LHD isn't as much of an issue as people who've not actually owned a LHD car will have you believe - although mine obviously isn't an everyday car.
Oh and I agree that they look best in blue...
They're brilliant..!
(oh and this is a pic from when it was new at Ian Allan - hence the no front plate..!)
That's rather nice.. smile

I really like these for some reason. Though I'd much rather have the Callaway Aerowagen conversion.

Excellent and detailed article.
A few small points to add l find UK/European cars are usually priced higher than personal imports these can be identified by the larger mirrors and headlamp washer jets and be wary of flood damaged or sometimes called Texas salvage cars imported from America a couple of years ago.

The wheel cracking issue only applies to Grand Sport and Z06 models from 2018 onwards l believe there was a magride software update that helped alleviate this issue.

As the report says try to avoid eco mode as much as possible as this can cause the 8 speed auto problems it may be wise to check if the transmission flush and oil change has been done under warranty as it can be quite expensive for the newer oil and labour.

Article said:
Despite those plastic leaf springs at the rear
This is incorrect and misleading.

Incorrect because the Corvette only has one leaf spring at the rear, not two.

Misleading because 'leaf springs' implies one per wheel, usually sharing wheel location duties with a solid axle.
OTOH, a single leaf spring is mounted transversely across the car. It's actually more like an anti-roll bar in layout and concept than conventional 'leaf springs' (and integrates anti-roll as well as supporting the car's weight).
The wheels are located by double wishbones, the leaf spring is a pure spring.

Bottom line, the suspension of the Corvette has more in common with a typical contemporary Ferrari in sophistication and behaviour than it does with old GT or muscle cars with live axles and leaf springs at the rear, Interceptors and the like.

Don’t be misled by reference to old school mechanicals however. Yes they have a push rod engine but the transaxle drivetrain, 8spd/7spd gearboxes, magnetic dampers etc aren’t something I’d ever expect to see on an old muscle car.
I believe they also leased out the design to other manufacturers as it was such a clever piece of engineering.

Precisely.

I have no vested interest in Corvettes, but it makes no sense to stereotype them as crude or technically retrograde when the facts just don't support that.
Thanks for the link and post, I'd never known what a clever piece of engineering it is. I think its a widely accepted legend that the Corvette basically has cart springs.

That was the Magneride system. Designed and developed for the Corvette C5 and Cadillac STS by a subsidiary of GM then used under licence by other manufacturers such as Ferrari for the 599.

one other point - the Euro Spec models will cost you more on road tax than a personal import (to be fair in the scheme of things it's not a lot but still worth mentioning)

Certainly is. C7 is lovely from all angles, I have always particularly liked the back view though. Just as well as it's what you would expect to see! Best looking Corvette since C4 for which I have a strange and unfulfilled want.

Thanks Andy and mac.
Just adding a 'gratuitous rear shot' - the black tips of the AWE aftermarket exhaust I have do set it off, too (just imho...!).

Also available in red. In fact mine is red inside and outside, thanks to being Manchester United's promo car.

It's a great write up and sums the C7 up very well indeed. Quite a few of us owners have had TVRs previously, it's a similar recipe but a decade and a half on.

I saw the C7 when it was released and found it achingly pretty and thought to myself....one day. Stumbled across mine by chance and bought it on the spot. Official servicing available from Parts USA in Stockport, Manchester. They also happened to have supercharged the one mentioned in the article. I believe it is reasonably straightforward job (a couple of days) to slap the charger onto the 6.2L V8 engine and adds 150-200bhp onto stock. With 466bhp and 460ftlb torque in a light weight car, the performance is already insane, but they have been tuned to 1500bhp in the USA.
