Bigger than an Aveo but smaller than a Corolla, this B-Class mini-crossover would join a segment of luxury-economy cars that includes the Audi A3 and upcoming BMW 1-Series. Even with recent dips in gas prices, high mileage vehicles seem like they will be a more popular choice for buyers for years to come. The current B, although not a huge seller, is already available in Canada, so Mercedes has some data on whether or not it might work. But with such a long lead time, anything can happen, and there's still a chance M-B could reconsider. We say bring it on. Who wouldn't want the Mercedes of economy cars? That is unless a smart car makes enough sense for your needs.
