I had issues with my car and was originally told it was the wheel barrel...I paid and it did not fix the problem. Then i was guaranteed it was the motor mounts..and it was not the problem...and i paid 420 to replace 2 motor mounts...now I'm being told it might be the be the muffler. I told the manager i wasn't pleased with the service and he offensively said girl please. The taller guys is very pleasant with great customer skills..but the so called manager is not.
