If a car is painted 3 or 4 times is it worth any more than a car that has only been repainted once if the final result is the same? no. That's like expecting to get extra money for the minor modifications he bought when he first had the car and then sold for a loss when he went for bigger upgrades. If i buy a jwt stage III chip for 200 dollars, and then sell it for 100 after i get a dynotune'd chip from ztuner that doesn't mean my car is worth 100 dollars more because it once had a part on it that i lost money on.
