With 25 possible variations, we can't possibly go into all the different models of Sprinter available. There are three basic types: passenger, cargo and chassis cab, available in three-quarter ton 2500 and one ton 3500 models. Two wheelbases are available (144 and 170 inches) and three lengths thanks to the 170-extended version, which offers an additional 15 inches of space behind the rear axle. Then there's height: Standard, high and mega roofs are available. Passenger versions are only available in the 2500 models with the 144 or 170 wheelbase versions and with the standard and high roofs, however we're sure there's an outfitter there somewhere who could bolt seats into an extended mega roof 3500 if you really wanted to.
