As with all used, or even new, cars - only time will tell, but you can't really go wrong when dealing with Nickey's if you're looking for a quality high/higher end car. They have a small but select and extremely nice selection of BMWs and Mini Coopers, almost always with low km and just coming off a lease. You can't really ask for much more when looking for a good used car.
Not only are their prices incredible, but when I inquired about what prices they could get me new winter rims and tires, they were able to get them for me at a much better price than I would have been able to get myself.
Great prices, great no pressure service, and great cars!
