Before your test

Three checks worth doing on a 2018 Adam

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 suspension joints 5.0% of tests

    “track rod end ball joint dust cover damaged or deteriorated,”

    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.

  2. Check the shock absorbers 3.5% of tests

    “shock absorbers has a serious fluid leak”

    Press down hard on each corner of the car and let go. It should settle in one bounce; if it keeps rocking, or you can see oil weeping down a shock absorber, that is the fault a tester will find.

  3. Check the coil springs 2.5% 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.

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 2018 Adam through its MOT

Across the 10 items that are recorded most often on this model, the average repair comes to £25–£61 — and 18% of those repairs are parts that cost under £30.
