Find another service option if you own a Mercedes. I took my car in because the top was not working properly, after spending 600.00, I was told I would need a hydraulic pump 1700.00 plus labor. I took it to an independent shop for a second opinion, within a short time James identified the problem as a broken wiring harness 96.00 labor 400.00. So unless you have more money than you know what to do with , go somewhere else. MB of Henderson is not your best option for service.
