I have been taking my Impala there for the past 3 years that I have had my car. Called today for a oil change and the cost has went up to $69.95 for just an oil change. That is just ridiculous. They have now lost me as a customer. Also every time that I went there for an oil change which I had booked an appointment for I would have to sit in their waiting room for 2 hours. Just tired of paying so much money and wasting my time.
