Mileage and MOT

MOT, from the government's MOT records (DVSA, the Driver and Vehicle Standards Agency), as of 6 November 2026: the latest record we hold ran out on 9 October 2026; ask the dealer for the current MOT.

It failed its MOT on 2 October 2025 (windscreen damaged but not adversely affecting driver's view; offside windscreen wiper does not clear the windscreen effectively) and passed later the same day.

Advisories at the latest test: windscreen damaged but not adversely affecting driver's view; rear brake disc worn, pitted or scored, but not seriously weakened; nearside front brake hose has slight corrosion to ferrule; and 5 more.

Mileage at that test: 40,811 miles. The advert says 40,000 miles, fewer than the MOT record, so ask the dealer which is right.

Advertised mileage is about 15,500 miles lower than the median mileage of a 2004 Jaguar XJ on AskCar.
