Test drove a cla 200 today and i can tell you its pretty rapid for a 1.3, and that was with 4 adults in it. dont know about the 180 as wanted the extra bhp. As for the cla its quite cramped with low roof line, but the looks and tech more than makes up for it.
Did they confirm the pack that comes with the 200 cla? Will it be the basic amg? Interested in the 200 myself going to test drive at weekend.
