My Experiences: I have a 2011 Sprinter passenger version that I purchased with 9300 miles on it I like it except wife hates the ride: wish I knew a source to get softer springs or Air Suspension. Get about 18-19 MPG (soft foot). Needs 3 Gallon Mobil 1 to change oil, plus cost of AD-blue urea fills. I plan to convert it to a RV when I retire in 5-6 years.
