Call me a cheap ass but ever since I got into working on cars I only usually by used parts. Some people think this is risky depending on the part, but I save an ass load of money. It may take a while to get the parts I want but you save so much more money by buying used. Some parts obviously you can't do that, but it happens. Unfortunately anyone who mods any car has to realize that it is NOT a turn around investment. The odds are you will lose alot of money after when you mod your car. If you think grand prixs are money pits you should try owning a honda. Just be glad you own domestic, it's way cheaper. I have it least 10k invested in my honda and I will be lucky to get a little more than half of that back, but in the end I will always mod because it's fun, and I love racing.
