I had groupons both times for oil changes and couldn't wait for appointment time. I brought my car in knowing they would get to it on their schedule. It was done promptly both times when I was expecting better part of a day to get done.
Got in right away even on a Groupon. They didnt try to upsell me with unneeded services. I asked they check for some things, and they did but only said one needed doing. Fair price on needed services. Friendly and good communications. highly recommend.
