With rising fuel cost in the US, people are considering more economical options. The problem with the B. Is it really that much better a car than say a Toyota Prius? If MB can sell a B-class with a base price in the mid-upper $20k range, then go for it.

Mercedes has a plant in Brazil. If they could build it there they might be able to do it cost effective enough to attract buyers. Or, badge it as a smart.

If MB could sell this in the US with a diesel engine, I would definately be a buyer.
