I bought mine with 30,000 miles. Initially, it performed well. At 56,000 miles altinator, starter replaced, heater quit. Heater, despite repeated repair remains unreliable. Many problems detected related to the coolant GM used. Most of the interior plastic moldings have worked themselves loose. Both front doors sagged and had to have pins replaced. Car jack rattles in storage. Brake rotors warped, were difficult and expensive to replace. Substantial play has developed in the steering. The engine is strong, but not efficent. Averages 16 mpg. Mass flow sensor replaced at 90,000 miles. Catalytic converter replaced at 96,000 miles. Lifters had to be replaced at 112,000 miles.
