Thanks for the ideas guys, that porsche 904 looks the nuts!
The decision has, however, been made for me. When I asked they guys to respray it, I said I wanted the engine bay to be as high standard as the exterior. I'm not going to put that crappy soundproofing card in it. So what did they do? They've only gone and stonechipped the interior!
So its carpeting all round I'm afraid!
