Easy to do business with. Funny sales person, he knew what he was talking about and was entertaining. The car is great, I spent a lot of time price comparing and shopping around and their price was good (obviously I wanted better but it was a good price). I've had the car for 9 months now and I've had no issues.
I was reading some of the reviews on this site and I don't think that they give a fair representation of this company. I've had no issues with the car and I've been using them for service. Their service is great. When I was there I overheard a customer ragging on the service person trying to swindle free service. It was pretty obvious to me that they were manipulating. In general I thought she (the service person) handled it professionally. I would have thrown the guy out.
I bought my previous benz from the benz dealer around the corner. They were professional but their price for any service was crazy. At least this dealership has reasonable prices for service. The Benz dealer charged me $420 to replace a tire with a bubble in it. I was so stupid, i could have gotten the same work done at Green & Ross for $200. That really ticked me off.
I was wondering why the other Mercedes buyer didn't take the car to Mercedes to deal with that warranty issue. You can't expect a used vehicle reseller to have deep expertise in another make. Sure I'll get my oil, tires and general service done by North York Chrysler (or Green & Ross, I priced it and North York Chrysler was close to the same), but if there is an issue with something more technical, I'll take it to Benz.
It's not like they caused the issue to the car and the old "the light went on when i drove away" story sounds a bit fishy to me. It's a used car, you save money but it's a bit of a crap shoot. If you are worried, buy a used car that is still in warranty (like i did).
