2004 Saturn ION, 33K miles, don't trust the car to be reliable after about 80K, never had problems with it, but just don't trust this particular car.
2001 Saturn LS200, amazingly reliable car. At 86K+ miles it's reliable and a pleasure to drive and I would take this car cross country and back. We've never had to do anything except normal maintenance on it--we replaced the battery in December, but after four years I'd expect to replace things like belts, batteries, tires, etc.
2006 Toyota Prius with 21K miles, so far so good.
