Black Mercedes, Ive seen quite a few postings from yourself on the forum and was hoping that someone local would eventually ask the question you did, thank you. Being new to the Mercedes ownership group I was uninformed as to where to take my vehicle for service with a trustworthy shop. Your recommondations would be greatly appreciated. The shop is called Karmac, located west end. As to the status of my vehicle now, from what I understand it still not preforming up to standards, they tell me it runs fine at higher rpms but is still rough at a idle. Plan on getting a detailed list of work done and calling a few independents to compare costs and return to them to dispute their charges.
