We do diagnostics on Mercedes autos only. If you are having an issue with a warning light or drive ability issue give us a call. We do not do general repairs only diagnostics. If you have spent money elsewhere and still have an issue you would be in good hands with us, no guessing as to what will fix your car. Prices depend on the depth to which we need to go and are reasonable. In average weather I will come to you at home or work. We do not replace parts to attempt a repair.
