Altho the Crossfire's interior door pulls would work great for scissor doors, the doors themselves are VERY heavy and probably too weighty for such an application.
On MTV's "Pimp My Ride" a young girl had her Civic pimped out with scissor front doors. During the process the bolts broke. These are not heavy doors. Plus no way could her Granny get in without help.....they just block too much of the opening. Real Lambo doors swing further up AND straight up and down. These retrofit doors have to be pushed out a couple of inches THEN they swing up. I'd be concerned that the doors wouldn't be easy to shut properly.
Cool idea but I think the X-fire is too nice to experiment on but I'd love to see it.
