I damaged the Cover pan steering rack system by a wrong turn in the mountains and was forced to take it to M-Service in Walnut Creek unexpectedly. They charge me $3500-... Which 2700 was in parts. Forced to pay it to retrieve my car but when I got home I called a few of the Mercedes dealerships In the surrounding areas and Verified how much The certified Mercedes parts were and found out that they overcharge me on each part...I WAS SHOCKED...ex: Mercedes dealership had one part for $1197- , M-service charged me $1888- for that part. When confronted him service to ask why such the mark up Scott replied “ it’s the bay area you can expect to pay more per part!” All seven different parts that they used to repair the car were marked up so badly I overpaid almost $1200 in parts. I’m sure it was because I was a single woman walking in there desperate and I do believe they did not think I was going to check what I was charged I don’t recommend them just stick to Mercedes dealership oh and by the way they charge over 200 for an oil change Mercedes certified dealership only charges 179 I should’ve known then ... beware!!!
