I’ve seen them come in different heights. The shortest one looks sort of like an oversize minivan or Ford transit and probably drives similarly.
A cousin of mine has a taller one as a work truck. He likes it because he can stand up completely and still have access to a workbench, tools and parts bins.
The North Charleston site has for years reassembled partly completed Sprinter utility vans imported from Germany as kit vehicles as a way to avoid steep U.S. import taxes. Strong demand for the vehicles from North American buyers convinced Mercedes-Benz in 2015 to invest $500 million over several years to convert the plant into a full-scale production factory.
Which is how automakers get around the “chicken tax” on imported trucks.
