BMW 6 Series

And because the M-division know that their customers - who are largely British by the way - will drive those glorious wheels right off the M6 Convertible, there are all the usual reinforcements to compensate for the lack of roof, plus additional stiffening on the underfloor, and important stuff like the suspension and bulkhead have also been strengthened.

They've even reinforced the engine supports to cradle the jewel in BMW's crown and surely one of the best engines available today, the F1-inspired, naturally aspirated, five-litre V10.

This high-revving, award-winning hunk of heaven is lifted straight out of the M5 sedan and M6 coupe and produces 372kW.

But the M5 and M6 have got metal lids on them. Can you imagine what this engine sounds like at full chat, especially when you are sitting in the driver's seat of the M6 Convertible with the roof down?

Holy shit, man. It's off the hook how genius it sounds. It's Chitty Chitty Gang Bang, Forest Hump and When Harry Ate Sally - pornography for the eardrums. The sound could start its own menaissance.

Send a boy through a long tunnel behind the wheel of an M6 Cabrio, tell him to drop it to second and then boot it, and his testicles would drop in a nanosecond.

You would also have a teenage joyrider on your hands because he would have pressed that M button with unconstrained glee, raised the power from 295kW to full beans 372kW mode, and be making like Schuey and working his way up and down the SMG seven-speed transmission with its 11 different shift patterns.

Impressively, although it weighs over two tonnes and is a whopping 220kg more than the coupe, this car still goes like the clappers. In fact, with a 0-100km/h time of just 4.8 seconds, it is only 0.4 seconds slower than the standard M6.

And you know what? It feels even more mental to be going so fast alfresco. People just don't expect to be overtaken by a convertible - they look at you as though they have just been burnt up by a tractor. I never thought I would ever say this about a convertible, but the M6 truly is a car for people who love driving. I had an absolute riot - it is so much fun to drive.

The steering feels nigh on perfect, and the amount of grip and stability at high speed is simply staggering. But it would take bigger balls than I have [technically none then - Ed] to deactivate the DSC and hammer it.

That said, the M6 Convertible definitely brought out my inner man. I blame the primal sound of the engine. And that's why I found myself smoking cigars and talking exhaust notes with the M-division's Dr Ulrich Brunke late into the night while all the other motoring writers had scurried off to bed.

Like I said, you can play on the porch with the puppies or you can run in the yard with the dogs. The M6 Convertible? Woof woof.
