Maintenance. Get it anywhere with a Ford or Chevy. With the Sprinter you have to find a Mercede$ dealer who also has the Sprinter software and diagnostic equipment - not all do - or a Dodge or Freightliner shop with it. Again even fewer of those do. If a Limp Home Code gets set on the Sprinter you only have 2nd gear and Reverse until you get to one of those dealers. Road service can't help. If it happens on Saturday morning nothing happens til Monday. The tow can be a few miles to several hundred.
Most of the time Sprinters perform well and have more cockpit room, by a large margin, are as quiet, or quieter, in the cockpit. and get 15-20 mpg. The wheelbase is Sprinter van narrow and you get a lot of rock and roll when you enter a street at an angle, such as leaving a gas station.
Loved to drive mine. That didn't compensate for the insufferable German over-engineering of the engine electronics. I've had Dodge and Ford Class C's, never a Chevy. Now drive an E-450 - crowded cockpit, hot on the passenger side, harsh ride, but when I want to go it does.
