I have a 2003 2 door Cavalier LS. It currently has 112,000 miles. The Ecotec engine is excellent on miles per gallon. In the 6 years of ownership, this vehicle has not been in the shop. I change the oil every 3000 miles with a synthetic blend oil 5w-20. Had the tranmission flushed every 35,000 miles. I put on new front rotors and ceramic brake pads on recently. Living in the chicagoland area, this vehicle started every day and its parked outside. I love the ABS brakes and traction control in the winter time. This vehicle is top notch in my opinion.
