Expert verdict
Tyres: 2.3× the national share
Tyres make up 44.8% of everything recorded on the 2021 Mercedes-Benz E450amg, against 19.8% nationally — 25.0 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.
- Falls short of its own age and mileage. Like-for-like, cars this age and mileage expect about 91.2%; this one manages 85.6% — 5.6 points below. Age is a fair excuse; this is not age.
- When it fails, it costs. Only 18% 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 2021 E450AMG
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.

Before your test
Three checks worth doing on a 2021 E450AMG
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 2.4% 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 wipers and washers 2.4% of tests
“wipers blade defective”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
-
Check the lights 0.8% of tests
“headlamp aim too high”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
