Autopia Europia

Featuring a roof-mounted racetrack outside and 56 separate bars inside, the 708,661 square-foot Autopia Europia in Istanbul, Turkey will be the largest car dealership in the world. Rather than racing, the rooftop track is expected to be used for new car test drives, free from the traffic the 6 million annual visitors are expected to create on the surrounding roads.
