Very poor, I bought a rather expensive new car with multiple issues which I ended up rejecting. When the replacement car arrived I went to pick it up to find someone at the showroom had actually reversed it into a wall (they blamed the transit but they would not have accepted a car with a creased rear bumper). They made good and had it sorted but there were then a slew of issues, visits to the dealership and an absurd amount of my time wasted. Staff there also seem to have delusions of grandeur, almost like they are better than everyone else but, I have news for them, generally the customer base you have are educated and professional so have a word with yourselves! I could go on all day but I will save something for the official complaint I am going to be making, I can safely say that I will never use this franchise nor will I buy a Mercedes ever again! For a premium brand they have excelled at showing poor customer service and contempt towards paying customers!
