Buying a used Mercedes-Benz Motorhome: what to check
These checks follow the Mercedes-Benz Motorhome’s own MOT record: the areas it fails on most often, and how that changes as the car gets older. None of them replaces a mechanic’s inspection, but they tell you where to look first.
The biggest drop in pass rate for the Mercedes-Benz Motorhome comes between 10–15 years and 15+ years old, from 82.7% to 76.3%. If you are looking at one in or just past that range, read its MOT history closely.
By mileage, the steepest fall is from 90,000–120,000 mi to 120,000+ mi: 76.1% down to 58.8%. Mileage matters as well as age, so compare the car’s recorded mileages with its year.
1. Lights and electrics
Recorded in 71.6% of failed Mercedes-Benz Motorhome MOTs.
Walk round with the lights on: headlights (dipped and main), indicators, brake lights, fog light and number-plate lamp. Check the dashboard warning lights come on with the ignition, then go out once the engine starts.
2. Brakes
Recorded in 52.7% of failed Mercedes-Benz Motorhome MOTs.
On the test drive, the car should stop straight without pulling or juddering, and the handbrake should hold it on a slope. Look through the wheels for scored or heavily lipped discs.
3. Suspension
Recorded in 18.4% of failed Mercedes-Benz Motorhome MOTs. 6.3% of tests at 15+ years failed on suspension, against 2.9% at 10–15 years.
Listen for knocks over bumps and speed humps, and check the car sits level. Push down on each corner: it should settle rather than keep bouncing.
4. Bodywork and corrosion
Recorded in 13.5% of failed Mercedes-Benz Motorhome MOTs.
Look underneath and along the sills for corrosion, especially near suspension and seat-belt mountings. Uneven panel gaps or mismatched paint can indicate accident repair.
5. Steering
Recorded in 13.5% of failed Mercedes-Benz Motorhome MOTs. Rare on young cars, but 4.7% of tests at 15+ years failed on steering.
The steering should feel precise, without knocks or play, and the car should run straight. Turn to full lock both ways and listen for clunks.
Check the car’s own MOT history. Averages describe the model, not the car in front of you. Look up its registration for past failures, advisories that were never fixed, and gaps or dips in the recorded mileage.
Ask for the service history. Invoices show what was done and when; a stamp alone shows less. See how to check Mercedes-Benz service history and what a service history check can tell you.
