Not sure if this has been posted before, but just been reading through an old copy of Autocar I have and found the original review by Chris Harris of the prototype
Couldn't find the article on-line, but here's the AutoExpress one. Although it's one of the other 5 prototypes, as Harris drove "4045", pictured below

Not sure what the colour is as doesn't look like SG. Also, they seem to differ from the production models in the following ways:
- no M-trak
- half-leather buckets (made of CF?)
- CF bonnet?
- no integrated "duck-tail" boot
