my dad has a couple of merc commercials - sprinter(312D & 315cdi)and a vito(111cdi), tell me something, why are the electrics on them so $hit?...they go through light bulbs, like there's no 2moro.....they do carry the weight well though- sometimes u forget theres weight in the back....i prefer the 312d old school(1999 "T" plate, with over 200,000 miles on clock and still pulls like a train)
