Took my 2007 Mercedes to them. Told them it had a noise that sounded like a power steering pump. They agreed, power steering pump was going out. Cost $860. Results, power steering pump wasn't the problem. They said this was my fault because I told them it sounded like the pump. Then they offer to replace the AC pump for a cost of $670 for the pump and they install it free. Big mistake not getting it in writing. They replace the pump and then tell me that they took the labor off the power steering pump but charged labor for the AC pump. Wonder if it had something to do with the fact that the AC pump was $200 more in labor. All in all I paid $1754 because of their incompetence.
