2015 BMW 6 Series Gran Coupe 3.0 640d M Sport Saloon 4dr Diesel Auto Euro 6 in Coventry

What this car costs to run

Modelled over 7,100 miles a year (DfT National Travel Survey, England). Ranges, not quotes — every figure here is an estimate.

Vehicle tax (VED)Registered 2015, so road tax depends on this car's official CO2 figure, which is not on the advert: £20 a year at 100 g/km or under, rising to £790 over 255 g/km. The CO2 figure is on the V5C: ask the dealer for it, or for the registration to check on GOV.UK. The rates by CO2 are in GOV.UK's vehicle tax band table

Depends on CO2

FuelOur real-world economy data does not yet cover a 3.0-litre diesel engine, so fuel is left out rather than guessed

Not estimated

Insurance (UK average)The UK average premium actually paid for comprehensive cover, £566 in Q2 2026 (ABI) — an average across every driver, postcode and car, not a quote for this one. Yours turns on your age, postcode and record and on the car’s insurance group. A 17–20-year-old new driver typically pays more than this average: see our guide to the cheapest cars to insure as a new driver, or the ABI figures

£566

ServicingFrom a minor service (£280–£450) to a major one (£550–£950) on a BMW, from Autoza's own servicing estimates by make, not survey data. Routine servicing only — excludes repairs and tyres

£250–£950

MOT test£54.85 maximum in Great Britain — the DVSA cap, and many garages charge less — with the first test on the third anniversary of registration. DVSA: 27.51% of car and light-van MOTs in Great Britain failed their initial test in 2025/26, and repairs are extra

up to £54.85

Total of the figures aboveLeaves out fuel, which we could not estimate for this car, so the real yearly cost is higher

£850–£2,400

Work out the vehicle tax with our car tax calculator (it opens with this car's year and fuel filled in), or put in your own mileage and prices with the running cost calculator. The CO2 figure is not on the advert. Once you have the registration, our free registration check reads the CO2 figure DVLA holds for it, where DVLA holds one.
