Mileage and MOT

MOT, from the government's MOT records (DVSA, the Driver and Vehicle Standards Agency), as of 8 November 2026: valid until 2 July 2027.

It failed its MOT on 10 June 2026 (offside front inner suspension arm pin or bush excessively worn straight arm (rear)) and passed later the same day.

Advisories at the latest test: nearside rear brake hose slightly deteriorated; offside rear brake hose slightly deteriorated; rear brake pipe corroded, covered in grease or other material.

Mileage at that test: 89,640 miles. The advert says 89,000 miles, fewer than the MOT record, so ask the dealer which is right.

Advertised mileage is about 16,000 miles higher than the median mileage of a 2006 Mercedes-Benz SLK on AskCar.
