BMW M3 - a supercar refined - In the cabin

The M3 is a genuine four-seater, with ample legroom for four tall adults. Although there's good headroom in the front, taller passengers will find headroom in the back a little tight.

A huge range of adjustment makes it easy for all drivers to make themselves comfortable, while the sports seats provide just the right balance of comfort and support.

The dash is similar to conventional 3 Series models, so it's simple and clearly laid out, but you'll have to put up with BMW's iDrive controller, which some find too complicated.

The boot is a generous size, but it's an irregular shape and the load entrance is on the small side.

Equipment levels are impressive - the M3 is definitely no stripped-out race replica.

Features such as automatic headlights and wipers, xenon headlights, part-leather sports seats, electric driver's seat adjustment and reverse-parking sensors supplement the basics of 18-inch alloy wheels, climate control and a CD player.

You have to pay extra for full leather upholstery, larger alloy wheels and electronic damper control.
