I'm really not crazy about the Art&Science design theme, and I'm happy that it's getting toned down. It would be nice if Cadillac picked a design and stayed with it, but I think that is also what one of their old problems has been. Previous Cadillacs have only had evolutionary not revolutionary changes.
As for modifying pictures, there's only so much I can do. I'm not an actual autodesigner.
I like the idea very much.....But I agree with Bruce as well.....The edgey look has grown on me a lot in recent months. The CTS, While still being too small I.M.O. is a good looking car particularly the Meaner looking CTS-V models I've seen. I really do like the 12/16 look too, Cadillac has a lot of interesting ideas right now and I hope that they can continue the trend towards better quality that they've been SLOWLY pursuing over the last few years.
The picture above is of a Twelve, not a Sixteen.
I don't think it requires shaved door handles. It's something extra to go wrong, and probably doesn't work that well in cold climates. Sometimes you need to get a grip (literally).
