I've been to Precision Tune twice now, and I think they have very good customer service and are honest. Both times I've used a Groupon for an oil change and both times I was in and out with almost no waiting time. I did make appointments both times though. When I've called on the phone to discuss other possible work I would need done on my car they've taken the time to explain things in detail which I really appreciate. I would definitely recommend Precision Tune Auto Care for car service and maintenance.
