Worst service possible. Needed to bring my car in for a mandated recall (a "free and necessary service" mind you). Staff was short and rude at arrival. A simple service at 830am turned into an all day affair. While waiting for a shuttle back home (again a "free service") I was told to take the bus instead. By 3pm service center called with extra diagnostic offer (at the tune of $150-250). I refused. Told me they would call when the car was ready. I called again at 530pm only to find they had closed for the day. Next day, still no call and a $140 fee for service I refused. Absolutely scam of a business.
