It draws on 6,886 priced BMW 3 Series adverts across different ages and specifications, as of 7 November 2026.

A 2020 BMW 3 Series with the 2.0 diesel engine is typically advertised at £18,500: the median of the 455 for sale on AskCar, as of 7 November 2026.

Mileage and MOT

MOT, from the government's MOT records (DVSA, the Driver and Vehicle Standards Agency), as of 7 November 2026: valid until 26 November 2026.

It failed its MOT on 27 November 2025 (front windscreen washer provides insufficient washer liquid) and passed later the same day.

Advisories at the latest test: nearside front brake pad(s) wearing thin; offside rear brake pad(s) wearing thin; undertray fitted engine cover fitted.

Mileage at that test: 49,844 miles. The advert says 47,350 miles, fewer than the MOT record, so ask the dealer which is right.

Advertised mileage is about 11,900 miles lower than the median mileage of a 2020 BMW 3 Series on AskCar.
