Mercedes-Benz G65 AMG

What car has all-flat glass, external door hinges, a design that dates from the 1970s and a 612bhp twin-turbo V12 engine under the bonnet? There's only one car fitting that description: Mercedes-Benz's freshly announced, and totally insane, G65 AMG. Tragically (or maybe not), UK customers won't be able to buy the G65, though: we'll have to make do with the 544bhp V8-engined G63 AMG instead. However, there is an alternative: hot-foot it to Brabus, which will shoehorn in an even more powerful (700bhp) V12 turbo engine for a cool half million or so. (Mercedes-Benz)
