Have you driven it over there? It's pretty good, although it can still be a bit jerky or awkward at lower speeds through the city. Not sure whether I prefer my 7 speed torque converter auto or not

BMW M GmbH is proud to be the world’s first car maker now offering a seven-speed Double Clutch Gearbox:

The M double-clutch transmission with Drivelogic allows both automated and manual selection of gears. In both cases gears are shifted at a rate and with a level of precision never seen before on a conventional manual gearbox or automatic transmission. At the same time the driver is able to enjoy the optimised gearshift comfort of the M double-clutch transmission while switching over whenever he wishes to a more active and dynamic style of motoring...

Mmmm M-DCT.

Maybe the next Z4M will have the 4.0 V8 and the DCT - if that was the case I think I'd have to look at getting one. Maybe they'll offer the 'box with the 335 engine?
