In your opinion what are the top 5 greatest sports cars ever to be built? Now, I suggest we have a few guidelines in the selection. The car has to have been out at least a year so it can be road tested. So that excludes our Gen 5, the upcoming 662 hp Stang, the F12 Ferrari, etc. The list should include the cars looks, performance, and character. My top 5 are: 1. Gen 4 Viper ACR 2. Bugatti Veyron 3. Porsche 959 4. Ford GT 5. Buick Grand National What say you?
