About the Mercedes Motorhome

Best and Worst Years

Of the years with at least 100 tests, the 2007 model has the highest pass rate at 95% from 155 tests. The 2006 model has the lowest at 84%. The 11 point gap means pass rates vary somewhat between years, but no year is dramatically different. Newer cars usually pass more often simply because they are younger.

Reliability Trend

Newer Mercedes Motorhomes pass their MOT more often than older ones, by 5 percentage points on average, which is mostly down to age and wear.

Mileage Across Years

The oldest model in our data (1990) averages 111,634 miles, while the newest (2011) averages 61,005 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.

Compared to the Mercedes brand average of 87%, the Motorhome is 10 points lower, placing it among the less reliable Mercedes models.
