I've had my car serviced at both BMW Canbec and BMW Laval and the difference is night and day.
BMW Canbec is a complete joke. Took me forever to get help and I had an appointment. Then it took me another 25min to get a rental car, and then they charged me $15... wtf is the point of $15.
BMW Laval has exceptional service. I was always in and out of there with a FREE rental car within 5-10 minutes. Everything was run so smoothly and everyone was so efficient and friendly. I dont have a single complaint about BMW Laval and I will continue to go there.
The only reason I would start going to BMW West Island is due to its proximity. It looks like a very nice modern BMW dealership. There is a huge luxury car market in the West Island. Kirkland, DDO, Beconsfield, Ile Bizard, Lakeshore, Dorval... all of these places have very wealthy individuals living in them that have wives, husbands, daughters and grand kids driving BMW's on a daily basis.
The only downfall I seeing if for the surrounding dealers like Laval and Canbec. My belief is that Canbec will feel the hit of this new new dealer instantly. I also happen to know that BMW Laval is doing well and are in no risk of closing or selling.
