BMW has dangled the entry-level 420i M Sport temptingly just below £40,000. Even our generously endowed M440i xDrive marginally undercut its older Mercedes-Benz and Audi competitors on price. In light of some favourable forecast residual values, the BMW should be competitive on monthly finance.

The 4 Series’ standard equipment tally is marginally more generous than that of the 3 Series, but buyers should expect to spend extra on the optional M Sport Pro package (which is the only way to add those adaptive dampers, among other things, from £2300), as well as a few other items.

The newer BMW is tipped to outperform both the Audi S5 and Mercedes-AMG C43 for residual value, although the difference isn’t huge.

Wireless smartphone charging, premium audio and a head-up display are packaged neatly in the Technology package (£1900) but you can cherry-pick some of those items individually to save a few pounds.
