Anyone fron the GTA (east part) or Durham region in Ontario, Canada know of a good shop that can do work on Mercedes?

Im gettin put off with the significant disparity in service item protocoul. I have talked to 3 different MB dealerships & each one is telling me I need servcing costing anywhere from $550, $750 & $1,100. All were provided with my VIN & I verbalized the service history (previously only by MB). I'd like to save a bit of $ as things are a bit tight right now.

thanks all for your help

There's a shop in Scarborough called Stuttgart Auto Tech. The guy who works there is old but he knows his stuff, he's a guru of sorts with over 45 yrs of experience. If you want good work and are not in a rush, this is the place for you. The address is 3220 Kingston Rd (Kingston Rd. east of McCowan), I can't find the card so I don't have the number, but chk it out.
