It looks like the cat is finally out of the bag. The official pricing point of the Mercedes-Benz CLA will be $29,900 (at least here in the US). The news comes via the leak of the MB CLA Super Bowl commercial which you can view above. If you watch until the end of the commercial you will see the billboard reveal the pricing.
CLAjose already started a thread regarding this issue here (thanks for the post!) and there is already some discussion going on there: http://www.mercedescla.org/forum/5-cla-general-discussion/69-2014-cla-class-starting-29-900-a.html
