What's wrong with the GTR? I think it's the cheap price, buff look and the amount of BHP and torque(taking price in consideration) you get that makes it such a popular car among people. Nothing wrong with that? I'm sure it's a fun toy. :p
Off course if I could choose whatever I want I'd probably get something like an Aventador or Veyron. Or if I where to go ALL out an 250 GTO. On a more realistic note tho, probably the new M5.
