Tyres: 1.6× the national share

Tyres make up 31.6% of everything recorded on the 2014 Mercedes-Benz 250, against 19.8% nationally — 11.8 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.

Before your test

Three checks worth doing on a 2014 250

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.

  1. Check the windscreen 5.8% 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.

  2. Check the coil springs 2.3% 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.

  3. Check the suspension joints 1.2% of tests

    “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.

What it costs to get a 2014 250 through its MOT

Across the 10 items that are recorded most often on this model, the average repair comes to £43–£106 — and 13% of those repairs are parts that cost under £30.
