They told me every 15,000 miles that my 2005 Chevy Aveo had no cabin air filter. After 45,000 miles I pulled the glove compartment out to check myself...I found a 45,000 mile filthy cabin air filter. I wanted my spark plugs changed at 30,000 miles. They told me I have platinum plugs so it wasn't necessary to change them. I asked them to check the plugs...They weren't platinum plugs. My clock stopped working. They replaced it...but shorted out my dash lights. I had an appointment to bring my car in to get a new timing belt, tensioner, and water pump. I even received a confirmation phone call the day before. When I arrived the next morning for my appointment...They were clueless as to why I was there. Nothing to indicate what was to be done or that I even had an appointment.
