If you’re after a stylish yet affordable coupe, the 6 Series is not the car for you. Let’s just say you could almost buy two basic 5 Series for the price of a single 6.

The 6 Series range kicks off with the SE which has 18in wheels, two-zone climate control, cruise control, leather seats, heated front seats, parking sensors front and rear plus a 10.2in infotainment system with sat nav and a DAB radio.

If you go the whole hog and order an M6, you also get adaptive LED headlights, four exhaust pipes, bigger brakes, a carbon roof, an upgraded stereo and sporty ‘M’ touches inside and out.
All 6 Series have traction control, stability control andthe usual selection of airbags. Automatic braking is available as an option along with lane departure warning.

As for security, Thatcham give it five stars for resisting theft and four for resisting being broken in to.
