I actually quite like it but agree with some of the above. As an exercise in engineering it's interesting but if you had that sort of money to spend (and I don't, not even close) would you buy one? Other than to play 'top trumps' with other hypercar owners I sort of doubt it.
I'm not sure you'd use it's performance on a track and I'm not sure you'd use it in the real world either, my guess is pretty close to 100% of them will be a museum piece which begs the question, what's all the fantastic engineering actually for?
Take this point re use in the real world - you need to open the roof as well as the door to get out so it has to be this folding system and can't be a canvass replacement as in the F50. When you take the roof off you can, as he says, store it "somewhere........" ie not in the car. So it's a Spider you effectively can't use as a Spider unless you're absolutely certain it won't rain that day. My guess is this won't be a snag as you can just store the roof in the covered trailer the car was brought to the event in but essentially I don't think anyone would go out for the day without the roof, certainly not in the UK, so what's the point?
Generally like the look, fantastic engineering I'm sure, real world use - not so sure.
