I quite like the proportions. It has a look of a petrol car rather than a Lego motor driven kitchen appliance. At least it is interesting.
I remember when Chris Bangle started to style BMWs and hated his original version of the 1 series with its flame surfacing, hideous, it looked like it had broken its back. But... after a while it looked fresh and original and the idea of these curved surfaces started to appear on other BMWs, perhaps in a slightly more subtle way, owing to the larger surfaces to work with, and I started to actually like them. Nowadays, we see these surfaces everywhere on all sort of cars, although perhaps BMW is now moving in a slightly different direction again.
So I say "go for it" Jag, go down swinging, or go home.
Mind you, I love elephants, but I wouldn't want to own one though.
