I have an crazy idea, Buy that Sprinter or a rear end or side damaged sprinter , Remove the engine and install into a W123 W124 W126 Body, you how awsome will this be, VERY FAST, SMOOTH, UNIMAGINABLE GAS MILEAGE. The size of the engine should be the same with a OM61x family engine, Am I right??? But the only obstical its dealing with the eletronics, sensors that fuel system and the drivetrain
