Tyres: 2.8× the national share
Tyres make up 54.7% of everything recorded on the 2021 BMW 420d Xdrve Msprt, against 19.8% nationally — 34.9 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 84.5% — 6.7 points below. Age is a fair excuse; this is not age.
- When it fails, it costs. Only 21% 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.

Before your test
Three checks worth doing on a 2021 420D Xdrve Msprt
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 tyre tread 1.8% 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 wipers and washers 1.8% 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 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.
