The O.P. was asking what we thought of it.
Personally I think it looks horrible and I'm entitled to reply in that way as we all are and several have.
To me it's as hideous as, say, putting a Cadillac grille and fins on a Jaguar E-type or a Ford Edsel grille on a Rolls-Royce. I see them all as true classic cars which should be cherished as 'special' for what they are and what they represent. But then, I wouldn't put IKEA furniture doors on an antique piece of furniture either or paint a moustache on the Mona Lisa.
Each to their own and those who think this Mini looks superb are equally entitled to reply in that way.
But it sure has de-valued it.
