They were shit. Now they're the best cars available these days. Can make more power with less fuel and cost than their Asian and European counterparts, and also reliable. Contrary to beliefs, they can actually turn, in fact they're one of the best handling cars ever. Corvette ZR1 and Dodge Viper ACR are slower than Nissan GTR, but they managed to smoke it on Nurburgring track by 20 buses length.
