I've been here twice. The first time was for an inspection, which like many other reviewers, was from a Groupon. You will notice when you walk in how clean it is. There is also free wifi, Keurig coffee, and a nice high table to sit at or if you prefer, a couch. The inspection took a little long, but the owner came out an apologized for the wait. He took care of a burned out bulb which ran about $3.
The next time, I scheduled an appointment to get, what I thought, was a worn wheel bearing looked at. I get a call about an hour or two later saying that my tread has separated from the tire and that I should replace the it. He quoted me a few different prices, but since I get my tires taken care of elsewhere I passed. They didn't charge me anything to look at it, and I briefly chatted with the tech that looked at it. I told him that even I'm not taking care of the tires here, I'll be back since I work close by (and the service has been honest and professional so far).
On a side note, I was also given a quote to get a valve head gasket done; it was almost the same price as another highly rated Charlotte mechanic shop, but Super Eagle added another $30 to the price for an oil change since they recommend doing one at the same time.
