So at least once a week, someone will ask what their car is worth. I will start off by saying, DE-MOD YOUR CAR! Your mods only lower your cars value. I know there are some mods that aren't too easy restore, but do the best you can. A clean, decently low miles, no rust Grand Prix is about $3000. That's all your gonna get. Maybe $3100. So all of you asking in the $6000+ range, keep asking. Let's say your car has low miles, but has a fair amount of rust. $2500 is a good price for that. These cars aren't expensive so you aren't gonna get a lot of money when you sell yours. If you want to get the most for your car, start at $3500 and see if people will bite at it. Anything more than that, you won't sell your car easily. Maintenance helps a bit with value, but not much. I hope this will reduce the amount of posts/new threads. Feel free to change the numbers if they are off, but this is what I've found to be the case.
