I have recently decided to look for a new car and have really liked the GXP models. There are a few mods I see, which I like. I just want some opinions on whemther this car is a good buy. It's a 2008 GXP with 52,000 miles and they are asking 11,900 for it. I looked it up on kbb and excelent condition was 13,000-13,5000. Since it has 52,000 miles on it already am I going to be running into problems? Is this a good buy or no?
