obviously there were noteworthy cars that came with gullwing doors.http://www.carmagazine.co.uk/Community/Car-Magazines-Blogs/Tim-Pollard-Blog2/Twelve-things-you-may-not-know-about-the-McLaren-F1/
according to that Murray have seen a sera & he got the idea about the doors,
however my original post was about the sera being a future classic,with limited number of production & pretty much half of that survives now. that is why I thought it should be a classic.
