The car is used and they wont add or remove anything. I can say one thing i would haggle for is a full "dealership" not third party extended warranty. Third party warranties are a scam. I went with my girlfriend to get her a 05 matrix xr. 35000 miles. They were asking 11500 she got them down to 10500 an 1500 for her POS. I got them down to 9800 ( they were charging her a delivery fee, mind you it was a trade in) she got an extended warranty through that dealer for up to 100k miles and free oil changes up until 100k miles. They removed some of the door dents and repainted the rear bumper from having small scratches.

Keep in mind if they were asking 11500, trade in was 9000 on the car which means they paid 15% less than that for it. So we met them in the middle and got some extras out of them for the car.

Since the car you are looking at is 24.5k and its value is 22k trade in is probably 19-20k and they paid around 17k for it. Id go in, offer 20.5k for
it, see what they can do, work on an extended warranty, dent removal, maybe new tires and what not.

Good luck.
