Those are butterfly doors. FAB Design will mod your SL (if you
have one) to butterfly doors for a fee. Best thing is it is
legal.
Do take note that modding your cars to scissors/gull/butterfly
doors are not as easy as it seems.
It may be possible, but the structure of your car frame was never
meant for it. The additional vertical weight of the door will
damage your frame. IN a few months, you will notice your door
wouldn't close nicely.
