Everyone is gonna tell you the car they have is better, whether it is or not. I've pretty much driven them all, Bailey, ERC, FOZ, and Henchcraft, and 100% honest, there is not much of a difference in any of them. Getting the right setup, engine, and driver combination will make any of the cars go fast.
Main thing to worry about is getting a strong, safe, structurally sound car. If it has been fixed, find out if it has been fixed correctly.
