Can a vehicle upgrade system (like fig. 1 below) be done during the game or would it totally screw up and not be possible. I wouldn't like 80 different vehicles (Jeep Steering 1 Brakes 3, Jeep Steering 2 Brakes, 3 etc...). If the method of modifying the actual vehicle isn't possible, is there a way around it.
