The BMW Z4 is a sports car that isn't know for corner craving, but instead for relaxed cruising. The compact convertible segment of the Canadian auto market has seen many entrants engineered to produce sheer fun. But the German automaker that is BMW has arguably hit the sweet spot with the BMW Z4; a car that lands squarely in the middle of the roadster playground. The upscale convertible with a retractable hardtop roof offers the best of both worlds-it's not nimble, but cramped traditional sports car, nor is it grand-touring drop top with a big engine and an even bigger price tag. In fact, it is ideally placed in between two. Acceleration from a stop is quick with a range of power options available. While not exceeding in any one area, the key is "balance" when it comes to the Z4 as it is one of the most well-rounded sports cars in the industry and walked away with this year retained value award.
