See what our customers from Irvine, Orchard Hills, Great Park, and beyond are saying about their experience with our Mercedes-Benz Service Center team.
I have been going to Mercedes Benz of Foothill Ranch for the service on my vehicle for the past few years. I have had such a great experience with the service department every time I take my vehicle in. I just came back from having service today and just HAD to write that I have had another AWESOME experience at Mercedes Foothill Ranch.
I feel like I’ve become friends with the people that work here. I have had nothing but amazing experiences with all the employees. From buying two cars to any service needs, everything has been exceptional.
Unlike many other dealerships I’ve dealt with, the service advisors here are always professional and explain everything to me without being condescending or pressuring me into purchasing something I don’t fully understand and may not need right away, as I am not a mechanic. I highly recommend this dealership for Mercedes service.
