In my particular case the car buying experience was flawless, so give these guys a chance and go see Kurt Holzinger.
I get my oil changes here. The service is always friendly. I have never been pressured to get maintenance done here that we prefer to do ourselves at home. When the oil change is going to take longer then I want to wait they will give me a ride to the mall and pick me up when the car is ready.
All in all very pleasant and easy to deal with. I normally service my Honda's with a smaller independent shop but I will use Honda of Plano again.
