Belated review. Bought the car in Dec 2016.
I bought a used 2013 Mazda 3 GS from Mazda of Richmond Hill (I believe formerly Avante Mazda). The GS was loaded with pushbutton start, leather, sunroof, upgraded Mazda rims, traction control etc and I got a great price on it. It was also Certified PreOwned so included reduced financing rates and extended powertrain warranty and roadside assistance.
The salesman (Michael) and Used Car manager were pretty easy to deal with. They were trying to clear a backlog of used inventory so I got a sweetheart price.
The dealership did go over and beyond since the car only came with 1 keyfob and they got and acquired a 2nd fob for me. I won't go into details but this was a long complicated process to get the 2nd fob but the dealership got it done. Some dealers would have just said "You only get 1 fob".

I'd recommend and would deal with them again in the future.
