With sedan, coupe, wagon, and convertible models, there's a 2011 3-Series for nearly any purpose, from focused sport touring to hauling the kids.
Up front, the seats are well-made and ample, with plenty of legroom and headroom even for taller adults. A unique seatbelt extender in the coupe makes it easy to find the front belt. The rear seats are less spacious, with both headroom and legroom compromised, particularly in the coupe and convertible.
Storage inside the cabin isn't immense, but it is sufficient. Cargo room is good in the wagon but only fair in the sedan, totaling 12 cubic feet in the trunk with the rear seats up. The coupe's trunk has a smaller opening that limits the size of items that can be stowed. With the rear seats folded down, both coupe and sedan can hold larger items. The convertible has even less space than the coupe due to the folding top.
