Depends if were talking bout regular old vette and a regular old viper or a ZR1 and a ACR viper if its regular one but to choose between the ACR and the ZR1 would be hard standard flat right rear tire or flat left rear tire?
How about no flat tires @ all cause fuck that. Would you rather have this Top Secret V12 Supra Or this Top Secret Skyline (RB26 i fink) Tough choice but i love that Supra (shits way fast with it's 1,000+ hp)
