I would have to do the GT-R. It just seems to spit in the face of everything else that's considered exotic. Cheap in comparison and would blow most of those away. Plus it can be driven daily unlike many of those.
Porsche 911 Turbo all the way. That thing looks fast just sitting there. I would be able to get many hood ornaments like Nak has on his truck!
If I was going to buy, it would be a Vette, but if get to pick one for free, it would be a Ferrari. I have been in love with Ferraris since I was kid, back in the '80s and saw my first Testarossa.
