Mileage and MOT

MOT, from the government's MOT records (DVSA, the Driver and Vehicle Standards Agency), as of 7 November 2026: valid until 21 May 2027.

It failed its MOT on 20 May 2026 (offside front brake pipe leaking on a hydraulic braking system; brake performance unable to be tested) and passed 2 days later, on 22 May 2026.

There were no advisories at the latest test.

Mileage at that test: 57,570 miles. The advert says 57,000 miles, fewer than the MOT record, so ask the dealer which is right.

Advertised mileage is about 8,200 miles lower than the median mileage of a 2004 Mercedes-Benz SLK on AskCar.
