Scissor doors! whoa hot. This form of door was first introduced in the Alfa Romeo Carabo concept car, designed by Marcello Gandini. The early reasons for this design were twofold. One reason was for styling, the other was make the driver's life easier when reversing. Since the car had very poor rear visibility, instead of using the rear view mirror, the driver could open the door and actually drive the car while leaning out. Gandini used the same doors in the Lamborghini Countach whose wide chassis mandated this unusual door configuration. The design was carried forward to the Countach's successor, the Lamborghini Diablo. The only current Lamborghinis in production which use this design are the Lamborghini Murcielago and Lamborghini Reventon.Lamborghini has now become synonymous with scissor doors.
