Upon mere outside glance the decision might be a difficult one, given such immediate similarity between the C and CLA.  As well discussed however, the numerous distinctions come from within the engineering of these two Mercedes-Benz cars, not to mention that other difference– the one from within your bank account.  Horsepower, drivetrain and rear headroom aside, talking pure looks in this case, I get the feeling I’d opt for the lower-priced CLA myself.  Et vous?
