Veeky Forums I need your help. I'm stuck between if I should get the GTR or viper. These would be weekend cars...

Neither.

Just buy the ACR. You'll have a piece of history as there will be no 2017 viper, it will give you the best performance on a track/canyon. Only thing it's slower to is 60 MPH

If you were actually in the market for these cars, you would test drive both and decide for yourself.
