Dodge Dart is a C
The Focus was dropped form C to B last year, which is odd as it is indeed in the same class now as the smaller Fiesta. Whilst it is consistent with the Golf also being a B, the other cars in B are all smaller, cheaper (and mostly nastier), so if you get a Golf or Focus, view it as getting a C car for the price of a B. Not that there is usually more than about a buck between B and C pricing anyway.
