The mechanic ""fixed"" my exhaust manifold. When I left everything seemed fine. Thirty-six hours later a loud noise happened when I pushed the gas pedal. I had a friend look at the manifold to get me up to snuff about what was happening. We called Manny's, both of us spoke to the mechanic. The mechanic didn't say, ""Bring the car in and let me look at it."" He indicated that whatever it was was not covered by the warranty. I then went to where I bought the parts. They looked at it and saw that the mechanic didn't torque the lower three bolts tight enough.
Cons: They didn't stand behind their warranty
