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.
How much does it cost to run a BMW 4 Series Gran Coupe hatchback?
Running costs for the entry-level diesel are pleasingly parsimonious. The 418d has a combined average of 62.8mpg and £30 road tax, which is very good for this type of car. The 420d has official fuel economy of 57.6mpg under the old NEDC test and £115 tax (the 2016 update improved this to 67.3mpg and £30).
BMW gives the name 'xDrive' to vehicles equipped with four-wheel drive. This is available on the 420d and 430d, and comes as standard on the 435d. You can also find it as an option on the 420i and standard on the 440i petrol. Models equipped with xDrive get a similar or slightly lower mpg figure compared with models without it. It’s worth finding an example with xDrive if you live in rural areas where it is guaranteed to snow in cold weather.
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 £150, 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 £475 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.
