Recently, I needed to take my Mercedes-Benz E 500 4MATIC to Chesterfield Mercedes for repairs and servicing. From the moment I dropped my vehicle off, my personal service advisor, DEANN, kept me fully updat to Chesterfield Mercedes for repairs and servicing. From the moment I dropped my vehicle off, my personal service advisor, DEANN, kept me fully updated on the status of the work being done. The certified technician performed a thorough assessment of the necessary repairs and provided me with both a detailed video walk-around and a clear verbal explanation of the issues. This was truly impressive, as I could actually see and understand exactly what needed to be done to make my vehicle safe to drive. All I had to do was decide which repairs to authorize, and the technician immediately went to work. To my surprise, the repairs were completed earlier than expected. Every member of the service department was professional, courteous, and exceeded my expectations. Service Manager AJ and Shop Foreman JIM ensured that I was kept up to date throughout the entire process. When I came to pick up my vehicle, everything was all ready to go. ADAM explained the bill to me in detail, and made sure I received all the necessary documentation. Integrity, credibility, and professionalism best describe the Chesterfield Mercedes-Benz Service Department. I highly recommend their team for anyone seeking top-quality service and peace of mind.
