I think they are calling this a concept to see initial reaction just in case they get the same response as the charger. They still have time to change any glaring negatives that come up.
That being said, my first initial reaction is
although it is almost too retro. I would have one in my driveway without a doubt
as is.
If they build it, I hope it doesnt become a laden down pig with options galor so it is a couch on wheels. Keep it simple and light. I am not suggesting things like no air conditioning, but we dont need power everything and cup holders on every panel. NO Mercedes wood interior/options crap for the "sophisticated" driver, it needs an interior for a driving enthusiast that is all business, no fluff.
