actually you are wrong here. i was a salesman myself. we used to have to take off money just because they an aftermarket head unit in. we deducted so much for every aftermarket part depending on what it was. if they took them off and replaced them with stock we would give them more for the trade.Ready2Play said:Dealer won't lower teh value due to the extras, but won't give any extra for them. My wife is a car saleswoman. Shoot me the full VIN, exact milage, and specs and I'll have her look into it.
