Best mercedes repair service?
Help us help you. Where are you located?
There is a good one in Fairbanks , Aklaska and one in Sydney , Austrailia .
Any well rated independent auto service shop that works on Mercedes will do fine. And be cheaper than a dealer.
If this SUV has upwards of 150k miles on it, I’d strongly suggest you get rid of it immediately. It will destroy your finances keeping this thing running much longer.
Ask other MB, BMW, Porsche owners where they take their vehicles for servicing.
