Mileage and MOT

MOT, from the government's MOT records (DVSA, the Driver and Vehicle Standards Agency), as of 7 November 2026: the latest record we hold ran out on 1 November 2024; ask the dealer for the current MOT.

It failed its MOT on 24 October 2023 (exhaust lambda reading after 2nd fast idle outside specified limits; nearside rear direction indicator incorrect colour; nearside front road wheel badly distorted; and 1 more) and passed 9 days later, on 2 November 2023.

Advisories at the latest test: nearside front tyre has a cut but not deep enough to reach the ply or cords; offside rear brake pipe corroded, covered in grease or other material; central oil leak, but not excessive.

Mileage at that test: 101,217 miles, which matches the advertised 102,000 miles.

Advertised mileage is about 36,800 miles higher than the median mileage of a 2004 Mercedes-Benz SLK on AskCar.
