Exhaust repair service near Charlotte, NC

Took my car in for an oil change and saw that they had a Groupon special. The Groupon was advertised as $29. The owner told me to ignore the coupon and he would give me the same price. His "same Price" Was $79.95. He said that he had to replace an oil drain plug, which on the invoice is only $13.98.

Came to my place of business. Found the problem, fixed it at reasonable price Pleasant to deal with. Knowledgeable. Honest. Really showed up local Ford dealership on price, knowledge, etc.

My wife took my truck in (I had out of state tags at the time) to repair the exhaust system. I had no other problems. The mechanic went on about how much my truck was "a piece of junk. Offer to sell us a car he had fixed up. When I got my truck back, I no have difficulty starting it, there is exhuast coming out from under the cab of the truck and I now have a leak in my transmission. None of this was happening BEFORE I took it in. This guy is either crooked or incompetent. I wont give him a second chance to prove to me which one it is.
