The "Vision B" concept, first unveiled last Fall in Paris, shows the styling of the production B-class range that we'll see later in 2005. Designed as a competitor to the BMW X3, the B-class is the smaller of two Mercedes-Benz sport tourers destined for production. Given the X3's tepid reception in the U.S., we're surprised that Mercedes is planning to bring this premium-cute-ute to our shores.
