There are plenty of American compact cars that would beat the socks off of alot of the Japanese compacts.
For one, any of the GM cars that came with the LGO 2.3L Quad 4. Research it, that engine has alot of racing history. Pretty potent engine from the factory. With the right mods? Watch out. Im part of a Beretta community, and theres a video on youtube of another member on there and his 92 Beretta GTZ with the Quad 4 beating a WRX.

I really think the '09 Chevy Cobalt SS Turbo would be a really good car in the game. 260 hp stock, that and GM took it to nurburgring to tune it.
But no, theres not enough room for those type of cars because that other skyline with a different spoiler should be in the game right? <-- Thats the pointless cars, the 27 extra skylines.
Rediculous.
i think anything under 100 hp is pointless in the game.
