I bought my RS @ Oakville Subaru. I would not say they can beat other dealers in terms of best price (every dealer will try their best to sell you a car), but you will be happy with their parts & service departments.
They are very "mod friendly" & dedicate to accessories (OEM & their own custom made stuffs). Even if you ask something they don't know about, they will turn to Toronto Subaru Club members & try to help you all the way.
If you are looking for a good dealer, Oakville Subaru should be one on your list!
