I think there is merit to what the OP is trying to articulate...I have noticed that people have been asking unrealistic prices for their cars, based on what they feel the mods performed are worth, i.e, people asking 10k plus for beat up EG Civics simply because they are K swapped. Just because you went out and spent an outrageous amount of money for a swap doesn't make your car worth what you have "invested' in it, as anyone who has been in the game long enough knows you almost never get back what you have put into a car.
