I bought my 04 Grand Prig GTP Comp G with 39000 about 18 mths ago. Luckily I also bought an extended warranty as well. When I finally checked the radiator fluid, the cooling system was full of redish gunk, a common problem with Dexcool. Do a search for Dexcool problems if you see anything other than clean antifreeze in the rad or reservoir. Mine cost around $3000 to pull the engine and rebuild it with new improved gaskets etc. I love the car, now has 50000, and other than now saying to service the ABS and Traction System, it has been great. The HUD is especially nice, but I never use the paddles to shift.
The price seems fair with those miles, pretty low.
