If purchasing a used 2010 Camaro (or any car for that matter), I would image that a buyer would NEVER think to ask such a thing as if the car was tuned, especially if buying that car from a dealership. It could be months or longer down the road when an unsuspecting owner takes his car in for a valve noise or blown motor and is given the bad news...
Sorry buddy, but you tuned your car.
"No, I didn't...what are you talking about?"
Well, our computer says you did
"Must have been the previous owner, but you guys sold me the car this way"
So, would it be a good idea for GM dealers to check their trade-ins (Not just Camaros) for tunes and NOT accept them if they are still under factory warranty?
