I think this may be key to finding out you most wanted car. Because if it satisfies all your want and desires in it's most stock form than surely it is the best car for you.
I think for me it might be the E36 M3 Coupe. I would love one with stock wheels stock paint stock interior stock wing stock suspension stock motor etc.
Most other cars I would like to own I want them in their highly modified state. Where as a M3 I might just add coilovers CAI exhaust and be perfectly happy with it.
