Ooh! love these threads as its how i spend most of my waking day anyway, thinking of these little conundrums!
As a young lad my favourite cars were UR Quattro, BMW E30 M3 & any red Ferrari!
Owned the M3 and still got the Quattro so they can be struck off the list!
1) F40 Ferrari- my favourite car ever!

2) BMW 2002 Turbo- retro

3) BMW E46 M3 CSL- probably the most sorted car I've ever driven

4) Alpina B8 E36- more mad than great, Alpina V8 in a boggo looking 3 series

5)Alfa Romeo 8C- best looking italian car ever?
Loads of other cars like Citroen SM Maserati, Ferrari 355, Sierra Cosworth 3dr,BMW 3.0 CSL,V12 E-Type etc etc the list would change everytime you ask me probably altho the CSL M3 & F40 are always top 5!
Alot of these cars are obviously out of reach financially (at least the italian ones are!) but I've chalked a few off already so far as driving or riding in them at least.
