Advisories to look for in a Vauxhall Adam's MOT history

An advisory is a tester's warning that something is wearing but has not failed yet. These are the ones written most often on the Vauxhall Adam, per 1,000 tests. If the car you are looking at has one of these, ask whether it has been fixed since.

  • Tyres: slightly damaged/cracking or perishing231.3
  • Shock absorbers: has light misting of oil219.8
  • Tread depth: worn close to legal limit/worn on edge213.6
  • Brake discs: worn, pitted or scored, but not seriously weakened95.7
  • Brake pads: wearing thin63.6
  • Sub-frame: corroded but not seriously weakened50.1

Checking a used Vauxhall Adam before you buy

Against cars of the same age, the Vauxhall Adam fails more often than average on suspension, steering and windscreen, wipers and mirrors. Start there.

  • Suspension

    Drive over speed bumps with the radio off and listen for knocks. Look at the car side on: a corner sitting lower than the others often means a broken coil spring.

  • Steering

    With the engine running, rock the wheel gently: there should be almost no free play. Listen for knocks on full lock and look for power steering fluid leaks.

  • Windscreen, wipers and mirrors

    Look for chips or cracks in the driver's line of sight, and test the wipers and washers. Windscreen damage in the swept area is an MOT failure.

Averages only take you so far. The specific car's MOT history shows whether it has already failed on any of these, how often advisories were ignored, and whether the mileage climbs steadily from test to test. Read our guide to reading a car's MOT history before you go to view it.

How these figures are calculated

Source: DVSA Anonymised MOT tests and results, 2025 release. We count first tests of cars and small vans (class 4) aged 3 to 20, so a car that fails and is retested is counted once. A failure includes faults fixed and passed within the same visit. The same age average weights the national failure rate for each age by how many Vauxhall Adam cars of that age were tested, so a model is never penalised for having an older fleet. Make and model are as recorded at the test; trim levels are combined. Full method and rankings.
