Car and Driver Comparison test between Chevrolet Corvette Z06 (E90), Nissan GT-R, Dodge Viper SRT-10 ACR, and Porsche 911 GT2 (997). I consider this comparo to be uneven because for the price of the 911 GT2, you can purchase the Z06 AND the GT-R. The Porsche GT2 is undoubtedly the best car here. The GT-R is also an excellent car. My personal ratings: Porsche 911 GT2- 11/10 Corvette Z06- 8/10 Nissan GT-R- 10/10 Dodge Viper SRT-10 ACR- 8/10
