They all have identical upgrade trees but slightly different stats. The wiki car pages should be correct now. No point in choosing the Nissan for anything. You need to upgrade both the Ford and Holden to PR 65 (718 gold each) to complete their series and that will allow you to use either to complete the supercar championship.
