One star is too high. I came in for a recall on the knock sensor and a oil change. They weren't busy and my car was parked in a bay right a way. After about one and a half hours I asked how much longer. Service person told me about fifteen more minutes. Thirty minutes later I asked again and got the same answer of fifteen minutes. Finally my car is ready and the service guy checks me out. I start to leave and notice a sign at the service desk that if you don't get your complementary multipoint inspection, then you're next oil change is on us. When I asked about it, the service guy printed it out for me, but told me that my next oil change wasn't free because he printed it out for me and I didn't leave. I made the comment that it was a no win sign. The service guy laughed and said that's right. I asked to speak to the service manager. The same guy came back and said he was on the phone, but to give me my next oil change free. Even with the next oil change on them, I don't know if I want to go back.
