58,761MOT tests in 2025

In 2025, 58,761 Vauxhall Adam cars had a regular MOT in Great Britain. 66% passed first time, compared with 73% for all cars of the same ages, which makes the Adam worse than average. Adjusted for age, it ranks 203 of the 217 most-tested car models.

That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.

Pass rate by age

At 6 years old, 78% of Adams passed first time (all cars that age: 84%). By 12 years, that figure is 63% (all cars: 66%). It trails the average car at most ages, most noticeably at 8 years (12 points behind).

What to check when buying a used Adam

Based on where the Adam fails more often than other cars, these are the checks worth making before you buy:

  • Steering: Feel for play or knocking through the wheel, and check power-steering fluid isn’t leaking. More
  • Suspension: Listen for knocks over speed bumps, look for leaking shock absorbers, and check the car sits level. Ask whether springs, bushes or drop links have been replaced. Repair guide
  • Visibility: Check the windscreen for chips in the driver’s view, the wipers for smearing and the washers for working jets. Repair guide

Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
