You maybe getting a 4 X4 Sprinter in the US

I think M-B is starting to feel heat from Ford and Fiat. The 2014 Sprinter is still top dog when it comes to features, but having AWD in the 2015 models would make it the best "B" chassis out there by far, just because it would not just allow for better off-road driving, but a little bit of higher ground clearance so a bump would be less likely to tear off a generator, tank, oil pan, or other low hanging item.
