Expert verdict
Tyres: 2.3× the national share
Tyres make up 45.9% of everything recorded on the 2019 Mercedes-Benz S-Class, against 19.8% nationally — 26.1 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 89.5% and this one manages 93.3% — 3.8 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 19% 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 S-Class
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 S-Class
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 windscreen 1.7% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
-
Check the tyre tread 1.0% of tests
“tread depth below requirements of 1.6mm”
Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.
-
Check the suspension joints 0.9% of tests
“ball joint excessively worn”
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.
What it costs to get a 2019 S-Class through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £41–£96 — and 19% of those repairs are parts that cost under £30.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.

| Tread depth below requirements of 1.6mm Tyres | Advisory | 12.2% | £45–95 |
