I have a 1997 chevy cavalier that needs work. It needs a new heater core and airconditioner. It has 144,000 miles on it and minor rust. It has some chips in the paint. It also has a stereo with good speakers. Sun-roof. The seats are in fair to good condition. There is also a crack in the dash by the speedometer and one under the stereo. What should I ask for a car like this.
