Reckon an F40 would be modern enough to get away with it, appraently good for 60 in 3.2, carbon fibre body, not too many electronics
The couple of people I have spoken to lucky enough to have driven an F40 have described it roughly like so:
Epic experience, so many sensations, amazing noise, brutal speed, no use for anything at all though as just too expensive to ever drive hard on a track and too unpleasant for anything else.
Even with a lottery win I couldnt afford to go crashing F40s so that rules out trackdays, so I just wouldnt buy one TBH.
Would sooner build something like a nutty v8 turbo westfield or similar that I can maintain myself. Or for that matter a turbo 355.
Cars to me are as much about building them as driving them, I enjoy doing it.
