What used BMW 4 Series Gran Coupe hatchback will I get for my budget?
Prices for an early 420d SE with a high mileage start at under £10,000. If you spend more than £11,000, you’ll find plenty of petrol or diesel 4 Series Gran Coupés with an average mileage from 2014 or 2015. The 420d is by far the most popular engine option and you will find that the majority of 4 Series Gran Coupés for sale are diesel. Spend between £12,000 and £14,000 on a good 2016 car, £15,000 to £17,000 on a 2017 one and between £18,000 and £20,000 on a 2018 model. Big bargains are to be had used and 2019 and 2020 cars can be had for between £20,000 and £25,000.
Petrols aren’t quite as efficient as the diesels, but the majority have smaller four-cylinder engines and use turbocharging to improve performance. The 420i has an average fuel consumption figure of 46.3mpg under the old NEDC test and £150 tax. If you want a bit more power, the 428i gets 42.8mpg and £190 tax. The 2016 facelift introduced the 430i, which manages 43.5mpg and £190 tax.
Top-of-the-range petrols are the six-cylinder 435i and 440i, and these are rather thirsty. The 435i gets 37.2mpg and costs a whopping £220 to tax, while the updated 440i xDrive is a little cheaper to run at 41.5mpg and £190 tax.
Under the later and more realistic WLTP tests, the 420i averages 44.1mpg, the 420d 61.4mpg, the 430i 42.2mpg and the M440i 36.7mpg.
If you are looking to purchase a car that was registered after 1 April 2017, then you will be charged under the new flat-rate fee of £155, unless you happen to be buying a 4 Series Gran Coupé that had an on-the-road price greater than £40,000, which is easily done for some of the M Sport and six-cylinder-engined models. For example, a 420d M Sport xDrive Auto that would have cost £135 before 1 April 2017 will cost you an eye-watering £490 afterwards.
You can get a five-year fixed-price servicing package on a new BMW car, so check whether the example you are looking at still has some coverage. Even if it doesn’t have any services left, BMW servicing isn’t the priciest around.
