As a small business owner with 3 Ford Econolines (gas) and 1 Sprinter (diesel), I'll take that question. :smiley_drive:
The Fords are less expensive to maintain and repair. Have you priced Mercedes dealer shop rates lately?
The Fords are less complicated mechanically - the Sprinter turbo just blew up last week, on a long drive hauling cargo. Happily, replaced under warranty, but not a pleasant thought post-warranty.
The Fords have more sturdy bodies - we rented the Sprinter out, and the renters failed to tie down stuff properly. The sliding stuff dented the Sprinter from the inside out...and dent removal places don't handle those easily.
If a renter whacks a door, we can find them in junkyards.
We live in CA - and diesels are problematic due to CARB regulations on them.
Our clients pay for the gas, so mileage is irrelevant to us.
So yes, there are instances in which the Econolines make a lot more sense than the Sprinter.
