Our experts predict that the M135 will be worth half its list price after three years and 36,000 miles, while adding option packs has no impact on used values. In comparison, the Audi S3 holds on to more of its value, but the Mercedes-AMG A 35 has residuals in the 44-48 per cent bracket.

Facelift has overhauled the M135’s cabin with a new dashboard layout and more tech
A clean look has been applied to the cabin, with the nav screen and driver’s display combined into a single curved unit, while the old car’s traditional air vents have been replaced by slots with the controls to one side. There are backlit grilles on either side of the dashboard and across the centre console, too.
Unlike some rivals that make the starter button a focal point, the M135 locates its on the centre console ahead of the drive selector. It seems modest to the point of being hard to find, if you’re not familiar with the cabin’s layout.
BMW’s M division stripes make an appearance as three lines of stitching running diagonally across the passenger side of the dashboard, but this feels like the in-cabin equivalent of the colours that some owners add to their car’s grilles.
The cleaner look is matched by decent materials, although the little joystick-style air vent controls that BMW now uses on its cars don’t feel quite as positive as the old vents when you’re adjusting them. As is typical in most BMWs, there’s a thick, squishy steering wheel rim to hold, while the synthetic leather and Alcantara-trimmed seats are figure hugging and comfortable.
Sat-nav, stereo and infotainment
The curved, twin-screen dash display comprises a 10.7-inch central touchscreen and a 10.25-inch instrument cluster, both featuring pin-sharp graphics. The new model does away with the old car’s iDrive rotary controller, so you’re left with touch inputs or voice control, which is a bit of a shame because neither system is as intuitive as the click wheel and shortcut buttons.
