My van is a 2008 Dodge Sprinter 2500 high roof 148" wheelbase with the 3 liter turbodiesel motor. It had about 200,000 miles on it when I purchased it late last summer. (On Craigslist--which I would not do again from a private party.)
Since it was "rode hard and put up wet" by its original owner (I am #3) and its issues were not disclosed to me by the prepurchase inspection, I would hope you use more sense than I did and make sure to look over maintenance records and engage a trusted knowledgable mechanic to look at it carefully. If this person is you, yippee!
Since it is the only van I've had, I can't compare it with other makes and models, but for living in, it is roomy and the high roof is wonderful. Still gets about 20+ mpg.
Good luck!
