Expert verdict
Seat belts: 10.6× the national share
Seat belts make up 8.7% of everything recorded on the 2019 Mercedes-Benz M8, against 0.8% nationally — 7.9 points above. Suspension is still the single largest share at 25.2%, but at 21.0% nationally that one is ordinary. Pull every belt out fully and let it retract: a frayed belt or a lazy retractor fails.
- Falls short of its own age and mileage. Like-for-like, cars this age and mileage expect about 89.5%; this one manages 82.8% — 6.7 points below. Age is a fair excuse; this is not age.
- When it fails, it costs. Only 11% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

What fails a 2019 M8
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2019 M8
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the coil springs 3.8% of tests
“coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
-
Check the brake pipes 3.2% of tests
“flexible brake hoses slightly twisted”
Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.
-
Check the suspension joints 2.5% of tests
“linkage ball joint dust cover ball joint dust cover no longer prevents the ingress of dirt”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
