What used BMW 6 Series coupe will I get for my budget?
If high miles don't bother you, early examples of the BMW 6 Series can be found for £13,500. If you spend a bit more, you will find some really good cars with less than 45,000 miles for between £19,500 and £20,000.
A 6 Series with a petrol engine is a rare beast, so be prepared to spend more if you want one. Budget around £25,000 for a 640i and between £26,000 and £29,000 for a 650i.
The M6 is in another league, both in terms of acceleration and cost. Put aside at least £38,000 for one.
How much does it cost to run a BMW 6 Series coupe?
Although BMW does fixed-price servicing on other models in its range, the 6 Series isn’t included. Still, the 640d will cost you the least to run and the savings are noticeable over a petrol 640i. The 640d’s official average of 52.3mpg and £150 road tax give it the edge over the 640i's 36.7mpg and £240 road tax.
The 650i is a little bit more costly with an average of 32.0mpg and £305 road tax. The M6, meanwhile, will cost you a small fortune to run with an average of 28.5mpg and £520 annual road tax.
If you are looking for a 2017 model, be prepared for a nasty surprise when it comes to road tax figures. Due to the high prices of the 6 Series, every model breaks through the £40,000 ‘premium’ tax level, which slaps an additional £310 onto the cost of road tax every year between years two and six of the vehicle’s life. This means that a 640d registered after April 2017 could cost you £450 a year, whereas one registered a month earlier is £150.
