I've had this car for five months and needed to replace the head gasket and coolant system. The car has run warmer than it should since I got it, and just recently finally decided to overheat. This car is only at 51,000 miles. Keep searching for other cars!
You had one problem with the car so that warrants a negative review? You owned the car for only 5 months and therefore you don't know what the previous owner did or probably did not do in terms of preventive maintenance. Most cars don't perform well when they are not properly taken care of. You will probably have another bad experience with your next car, too.
