The Chevrolet 3100 is a 2-seater (single cab) or 3-seater (with bench seat) classic pickup truck. For buyers considering the Chevrolet 3100, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
