With an average of 107,692 miles at 34 years old, MERCEDES HYMER owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

Diesel cars of this age should have their DPF (diesel particulate filter) checked, as replacements can be costly.
