I've just spent half an hour on the Sprinter section on the Mercedes forum (which is nicely done in a similar format to our own). It's all problems, issues and grief! I'm presuming you've had a look at that? I'm very happy with my 6.1, but I am easy to please, unless you talk to wife number 1...Not in the slightest! From heater temp not working properly to (Dodgy DSG) then all the other transporter gripes made me think are these really worth the money? Where the sprinter has 3 times the miles trouble free ? I'm not paying strong cash for an unreliable van again !!! Next conversion for me is sprinter hands down! More smiles per miles
