One of my concerns with the ribbed hood is that it may make the car look dated in a few years.
I think vehicles like the latest Mustangs and Caddies will look dated in a few years - I know that their styling is more fashionable/chic/in vogue etc. so it will definitely date.
I think the rib in the center would look out of place on it's own without the grooves, and the lack of grooves would leave a large expanse of very plain looking metal.
Until that day, I like it - and on a day like this I can watch the rain shoot up the grooves when I'm moving - it's real purdy!!!
