What Advisory (MOT) means for you
An advisory is a warning on a pass. The car passes its MOT, but the tester has spotted a part that's wearing and may fail next time. Common advisories include tyres near the legal limit, worn brake discs and thin brake pads.
Treat advisories as a repair list. Before buying, get a quote for the work and use it in your price talks. Tyres need at least 1.6mm of tread across the central three-quarters, and brake pads fail below 1.5mm. Check the MOT history: an advisory that appears test after test has been left alone.
