1st time using Your Mechanic and it was a great experience. Scott was punctual, friendly and took care of the oil change without any issues or surprise additional costs that you fear at a dealership. The savings (vs. dealer) + the entire process was very seamless and I'll definitely be using Scott's services moving forward.

Peter was fantastic! Very professional and knowledgeable about Mercedes. He spent a lot of time going over what the issues were with the car and what was needed. Overall we were VERY happy with the service and will be using it - and Peter - again very soon.
