What MOT means for you
Read the MOT history before you buy. It shows the mileage at each test, and a drop between tests is the classic sign of clocking. Defects are dangerous (fail, don't drive), major (fail), minor (recorded) or advisory (a warning). Advisories flag upcoming costs, like worn tyres or brake discs.
Driving without a valid MOT risks a fine of up to £1,000, unless you're driving to a booked test or to repairs. You can book up to a month (minus a day) early and keep your renewal date.
