It draws on 165 priced BMW 6 Series adverts across different ages and specifications, 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: the latest record we hold ran out on 30 March 2026; ask the dealer for the current MOT.

It failed its MOT on 31 March 2025 (front lower oil leaking excessively from engine covered by undertray cannot be fully inspected; offside front anti-roll bar linkage ball joint dust cover no longer prevents the ingress of dirt) and passed later the same day.

Advisories at the latest test: front tyre worn close to legal limit/worn on edge offside and nearside cracking; nearside rear lower exhaust has a minor leak of exhaust gases exhaust box; rear tyre slightly damaged/cracking or perishing offside and nearside.

Mileage at that test: 93,680 miles, which matches the advertised 98,000 miles.
