I would have given 5 stars except for one thing: they over-inflated the tires on my Porsche! They were uniformly at 40 PSI but should have been 29 or 34 PSI (front, back). Fortunately, I was at Big O getting tires on another car and my husband picked me up in the Boxster. As long as we were there, he had them check the pressure on it. Other than that, I love these guys. They are quick, efficient and always have provided great service!
