Expert verdict
Tyres: 1.5× the national share
Tyres make up 29.8% of everything recorded on the 2018 Peugeot 308, against 19.8% nationally — 10.0 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 87.9%; this one manages 84.9% — 3.0 points below. Age is a fair excuse; this is not age.

What fails a 2018 308
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 2018 308
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 lights 3.5% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
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.
-
Check the tyre tread 1.7% 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 1.7% of tests
“linkage ball joints 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.

Across the 10 items that are recorded most often on this model, the average repair comes to £24–£60 — and 43% 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 | 18.2% | £45–95 |
| Brake discs in such a condition that it is seriously weakened Brakes | Advisory | 12.2% | £45–110 |
