The second-generation CLA is a desirable piece of eye candy and is also one of the more affordable vehicles in the Mercedes-Benz lineup. Before diving in, however, there are certain practicalities that should be considered. You see, the CLA is a bit of a head scratcher. For most buyers/lessors, the four-door car likely makes more sense than selecting some two-door model. However, the head- and leg-room-deficient rear seat in the low-slung sedan — that Mercedes-Benz insists on calling it a coupe — isn’t suitable for taller occupants.
