BMW M4 Convertible revealed. Price from £60,730

A direct replacement for the old M3 Convertible, the M4 Convertible will cost you just over £4k more than the M4 Coupe, but for the extra money you get the same car but with infinite headroom – and a big weight penalty. The new 3-piece metal folding roof can be tucked away in a mere 20 seconds at the flick of a switch, with better noise insulation than the M3 Convertible had and more room in the boot when the roof is down too.

Not just the usual nip and tuck you’d expect in a mid-cycle facelift, but real sheet metal changes and proper upgrades as well as the usual lights and bumpers stuff. But however many photos we publish of the 2013 E Class, nothing really gives you a feel for the changes until you see them in the flesh or on the move.
