Scissor Doors & Butterfly Doors

Scissor Doors:
            Scissor doors are doors that rotate vertically upward, and are hinged at or near the end of the windshield.
Butterfly Doors:
           Butterfly doors are a type of door that are similar to scissor doors, but while scissor doors move up, butterfly doors also move outwards, which makes for easier entry/exit, and saves space.
