Nothing says "happy birthday" like 700 horsepower and nearly 1000 lb-ft of torque. That's what Brabus figures, at least, and we're with them. To mark the 30th anniversary of the indomitable Mercedes-Benz Gelndewagen, Brabus presented the G V12 S Biturbo here at the Geneva Motor Show, and it could hardly be missed in the middle of the Palexpo show floor. The tuned twin-turbo 6.3-liter V12 sits in a tricked out G-Wagen decked out in black with LED headlamps, custom bodywork, black leather everything, a 163-mph top end and a physics-defying 4.3-second spring to 60 mph. At nearly half a million on the sticker, you're not likely to see one parked at the local mini mall – unless you live in car-bonkers Abu Dhabi where a supposedly McLaren-powered G-Wagen was spotted last year .
