My add blue tec light came on in my car. So I made an appointment at this dealership. It ended up costing me $408 so they could add blue tec and 3 days without a vehicle. 3 DAYS!?! They told me, because the light came on, they had to do a diagnostic test. They nickel and dime you, until your bill is hundreds of dollars. The fact it took 3 days for something, that is almost as simple as adding oil, says it all.
I found the staff pompous and arrogant.
I had the exact opposite experience at Oakville Mercedes!
