Perhaps no one has told Mercedes-Benz that folks don’t take too kindly to wagons around these parts. Or maybe it’s exactly that kind of exclusivity the company is aiming for with the ’12 E63 AMG Wagon and its imminent debut in the United States. People, pets and paraphernalia can now be rocketed down the road thanks to a twin-turbo, 5.5-liter V8 making 518 hp and 516 lb-ft of torque, or 550 hp and 590 lb-ft with an optional performance package. Other niceties include a seven-speed transmission and a panoramic roof.
