I do have a soft spot for simple cheap cars like Micra, and it's cool Nissan sells it in Canada. I bet repairs and parts are cheap as well, so as an urban or suburban runabout, it's great. And it'll fit into any parking spot, and you won't have heartache when it gets scratched up or someone puts a door ding.
That said, like you guys said, the depreciation, or lack thereof, makes a used one a bit of a harder sell versus just buying new. Not only has the car only lost just 3k of its value, but upcoming maintenance eats up a chunk of that savings.
