If I were to make something similar I think that's how I would do it, to have the cowl panel still seperate from teh ood and have only that flip up.
I think the builder was looking for a very smooth look, and combining the cowl, service panels and hood into one large part, definatly does make it a bit smoother.
The car has some VERY VERY nice touches, some I like, some I don't, overall it is very well thought out and the execution looks to be very good as well.
