I've been a customer of QTS since August 2011. Since then I've only had to bring my car in a few times for regular maintenance unlike the last place I did business with. May 8th I had an HID kit installed under warranty because the other 2 failed. They honor all work under warranty and understand if your on a budget in these hard times. John and the rest of his staff are very personable with customers. If you happen to run into any issues they make you first priority and rest assured to make you happy. Also included is 24/24,000 mile warranty packet they will give you. 5 stars!
