How to Check an MOT (And What It Actually Tells You)
Checking a car's MOT history is free and instant, yet it's the most powerful tool you have when buying a used car. It tells you not just if the car is legal, but how well it's been looked after.
1. Read the failures, not just the passes
A fresh 12-month MOT doesn't mean a car is perfect. Look at why it failed previous tests. If a car repeatedly fails on bald tyres, worn brakes, or blown bulbs before finally passing, the owner likely scrimps on basic maintenance and only fixes things when forced to.
2. Trace the mileage history
MOT records are the easiest way to spot a 'clocked' car. Check for sudden drops in mileage between years, or periods where the car did suspiciously few miles. A car clocking 15,000 miles a year that suddenly drops to 2,000 a year right before sale warrants extra questions.
3. Look for the 'danger signs'
Watch out for structural corrosion (rust) mentions. If a car had an advisory for 'corrosion near suspension component' three years ago and it hasn't been mentioned since, check if it was properly welded or just covered in underseal to hide it from the tester.
4. Understand the tester's language
Testers use specific phrasing. 'Play in steering' or 'worn suspension bush' means a repair bill is coming soon. 'Oil leak, but not excessive' means the engine is losing oil, which could be a cheap gasket or a massive internal failure.
