Size matters, but so does power-to-weight ratio and the suspension setup. Even small economy hatchbacks without decent sound proofing can offer you a more exciting driving experience than a much more expensive and powerful ride that your buddies would call a "serious" car.
I draw the line at 1100 cc. That's a 67.12 cubic inch engine. Everything under it can play in this round, and three-wheelers are fine too. So show us which car can make the most of its tiny cylinders!
