....thanks for the dig! I was suggesting the drag car for the track...now that you have made your intentions for this second car clear, I would suggest a number of other cars which are fun, older, good power, and somewhat rare.
On my short list of 2 door fun cars:
Audi Coupe (Kinda rare and fun with a good turbo and Quattro)
VW Corrado - Both the engines have their problems but the VR6 has good power
Volvo Bertone coupe (840 I think) - Huge rare and heavy...
I'm sure there is more...but I'll stop there as I'm supposed to be doing homework....
