Ditto on all the above said. I would do a search on this model. There is plenty of info for sure. I am currently going to replace my OVP relay and have already had the head gasket replaced. Gauges seem to stick if it gets cold at night. I'm a little disapointed with some of these aspects, but the car drives great and has a powerful engine. I would have it checked first, and see if some of the problems have been resolved. Mine had all books and records through 54k and still had problems. I don't think I would have purchased the car without the help I've gotten from this site however. Good luck.
