6: Mercedes-Benz Sprinter
The Sprinter was a surprise for Mercedes-Benz in the United States, completely changing the delivery van segment as we know it. These big diesel vans aren’t cheap to maintain, and when it comes time to repair, you will spend a large amount of cash (via Motor 1).
The most recent incarnations of the Sprinter have suffered from many transmission issues, as well as a fair share of overheating problems. Because this is a Mercedes-Benz product, you will feel that when the repair bill comes.
