If it isn't what the previous 2 replies are saying, perhaps the 'Auto mechanic' who you can use to save the state of the car if you win a race - the other 2 being fame agent and manager. These appear when you select a race and before the light turns green. Other than this, I'm at loss to what mechanic you mention.
