one of the coolest cars every made was the Bugatti EB110 (also made in the EB110s, and ss models) It also has the window within a window, it really is the parent of the new Bugatti Veyron... (EB stands for the original something Bugattis name, 110 for the 110th anniversary and the S models were "sport" models that were lighter and the SS were lighter and more powerful) Basically the car was an amazing piece of machinery with a 3.5 liter V-12, quad turbo system made over 500 hp, and over 600 with the ss version and AWD to put the power to the pavement... only cost a half million or soo too
By the way the Lamborghini Countach i think had really small split windows too or maybe it was the diablo.. can't remember right now, although i'm thinking it was the Countach.
