Yep, the usual places that you find rust on the B13's, you can possibly find rust on the B14's. One benefit that the B14 has, though, is that it's newer, so your chances of finding a rust free B14 are better. Obviously, like any vehicle you purchase, you want to find out the history, as far as where the vehicle spent most of it's time. For instance, I personally like to find vehicles in the southwest, west, and sometimes in the midwest.
Finding one garage kept is an obvious choice
