I have a sprinter lwb and it has just notched up 100,000 with a few minor problems(gearstick snapped,engine managment light problems), ,they are by far the fastest van on the road but the downside is they are made from crap metal and rust ,mine is an 02 model and the rust is showing .had the reno master before that and thought it to was an ok van but did suffer a few major probs(gearbox) .if size is not an issue i would buy the toyota hiace or the v/w .if its a bigger van you want the new transit or the merc are both good vans but the new transit would be my choice if i had the money.if its a used van thats done some miles the sprinter would be my choice ,you only have to drive up and down the m20 a few times to see were the wise money go,s it is full of sprinters as they are the choice for the long haul companys wereas the transit is very much the builders/tradesmens van .
