What used BMW 6 Series saloon will I get for my budget?
You can pick up a 6 Series Gran coupe for as little as £12,000 to £14,000, but it'll have a high mileage. A relatively clean example of the 6 Series Gran Coupé will cost you nearer £16,000. This would net you a 2012/13 model with an average mileage for the year and a full service history. Up the folding to between £18,000 and £20,000 and you’ll find plenty of good cars from 2013 or 2014 with the same criteria, bought from an independent dealership, while £20,000-£25,000 will find you in the driver’s seat of a 2015 or 2016 car. Beyond that, good 2016 and 2017 cars will set you back around £25,000, and around £30,000 for good 2018 and 2019 models.
How much does it cost to run a BMW 6 Series saloon?
Quite a lot is the answer – although the diesel-powered 640d is the cheapest version to run by a country mile. Stick to SE spec with 18in wheels and it’ll emit a respectable 152g/km of CO2 and the official combined fuel economy figure is 49.6mpg. Meanwhile the petrol-engined 640i emits 178g/km of CO2 on 18in wheels and can only manage an official fuel economy figure of 36.2mpg. Don’t expect any V8-engined car to return much more than 20mpg in real-world driving.
Any 6 Series Gran Coupé registered after the tax changes that came into force in April 2017 will pay a premium over the flat-rate annual charge, because all models cost more than £40,000 when new. Expect a reasonably sized bill for those registered before that date, too.
Servicing costs are likely to be high, especially at BMW main dealers. The firm provides service packs for older cars that allow you to budget for future servicing costs and pay by direct debit. Older cars could be looked after by one of any number of independent specialists that are likely to do the work for far less money.
