It draws on 571 priced Mercedes-Benz S Class adverts across different ages and specifications, as of 4 November 2026.

Mileage and MOT

MOT, from the government's MOT records (DVSA, the Driver and Vehicle Standards Agency), as of 4 November 2026: valid until 7 April 2027.

It has had one MOT, on 8 April 2026, and passed.

There were no advisories at the latest test.

Mileage at that test: 19,795 miles. The advert says 900 miles, fewer than the MOT record, so ask the dealer which is right.

Advertised mileage is about 23,800 miles lower than the median mileage of a 2023 Mercedes-Benz S Class on AskCar.

The advertised mileage of 900 miles looks wrong for a 2023 car; check it with the dealer.
