The popularity of this option might be influenced by the fact that it's a standard design feature these days on a lot of cars. My wife's 1999 Accord has it along with my 2006 Mustang.
I don't think so. The newer cars have a more functional version that opens into the trunk. I can't imagine why anyone would want their classic to resembly these newer cars. I do see the resemblence to some of the older two seater Vettes. I think the major 'interest' that has been mentioned at car shows is your basic fascination with gadgets and gimmicks in the older cars...
