We been using GP Auto for about 7 or 8 years now and we have never had an issue. We have a trailer and four other vehicles, so we go there a lot, and we are very familiar with Paul's work ethic.
We go to GP Auto for all of our regular service and major service needs, including tires, batteries, and any major work like radiators and air conditioning. You name it, we've done it. And, they are very accommodating. They service you the same day you go in.
