Reviews
Brought my 2016 E Class Wagon for routine service on May
Brought my 2016 E Class Wagon for routine service on May 6, 2025. The mechanic found some safety matters that my vehicle definitely needed and I was unaware of. My service advisor Stephen Lopes coordinated the service with the safety work. Steve set things up to get the additional work done and not to inconvenience me by supplying a vehicle to use. Highly recommend Mercedes-Benz Flagship Motorcars.
