Thats why i keep all the stock parts i remove. If you throw em back on and sell the aftermarket stuff youll make more money and youll get the same price for the car cause nobody will notice.
But even if some crazy rich guy were to offer me $100,000 for my car cause his daughter wanted it, i would turn it down. I dont want somone like that to drive something i love so much.
Example from work: I work at a mall and we have little kiddy carts/strolers and they retail for $625US each. We had one guy ask if he could buy one because his little 4 year old daughter wanted it. He went and just wrote a check and walked out with it. Its people like that i wouldnt want owning or driving my car, ever.
