We imagine that if George Clooney and Keira Knightley ever got together, they would have the cutest kids ever. Similarly, if BMW tagged up Zagato, the end result too would be extraordinary. Fortunately, we don\'t need to use any imagination to picture that outcome because Germany and Italy really have joined forces to produce this, the BMW Zagato Coupé. Or as we like to call it, the prettiest thing on wheels. The dreamy two-door beauty has just been unveiled at the ultra-exclusive d\'Este Concours d\'Elegance on the banks of Lake Como in Italy. The sleek looker, a one-off, has been built entirely by hand and features an aluminium body that has been bathed in unique Rosso Vivace paint (bright red to you and me). We love that long bonnet and the muscular rear end, better known as the ‘Kamm tail\' (named after a boffin who\'s quite good in aerodynamics, apparently) but arguably the best thing about it is the iconic double-bubble roof, Zagato\'s signature design feature. But it isn\'t all about the Milanese coachbuilder — there are plenty of BMW cues too, such as the twin round headlights that sit between the trademark kidney grille with a matte finish. On closer inspection, it reveals Zagato\'s attention to detail — there are hundreds of letter Zs in the mesh! The two air intakes in the bonnet are a nice touch too. Around the back it\'s got a meaty-looking diffuser, matt-finish exhaust tips and it rides on five-spoke 19in wheels, also finished in matte with chrome BMW and Zagato badges. The interior is swathed in two shades of grey leather, one light the other dark, while the red stitching on the dash, seats and doors, sets it all off nicely. The headrests are particularly fetching with the letter ‘Z\' embroidered on them. Very tasty. Now the silly part. Joining the car are two exclusive matching Zagato accessories, a hat bag and a travel bag. Why? We don\'t really care. Let\'s focus back on the car. Sadly, the boys from Bavaria are tight-lipped about the drivetrain (all bets are on the Z4) but have been busy putting it through its paces in its own testing facility, meaning this thing does move. It\'s also been registered for road use. What we want to know is, when can we have a go?
