The 4 Series Gran Coupe trim line-up mirrors that of the Coupe, with SE, Sport and M Sport trims, with pricing starting from around £32,000. Entry-level versions get leather heated seats, xenon headlamps, LED rear lights, a parking radar, as well as climate control, so although the prices are around £3,000 more expensive model-for-model than the 3 Series, you do get more gear. The xDrive 4WD system is an option for buyers of the 420i, 420d and 430d derivatives - and it's standard on the top 435d variant.
Satellite navigation is standard on most versions, but the adaptive dampers are a box you might want to tick on the options list, as well as the sport steering. We could take or leave the sports seats, but the stereo upgrade is worth giving a listening to. BMW will also tempt you with a range of Connected services, a head-up display and some neat driver aids but you'll need to keep an eye on the asking price. It's easily possible to spend around £38,000 on an M Sport 420d with an auto box, add a few options and end up having spent more than £40,000 on a four-cylinder, two-litre diesel hatch.
