Last one, I forgot: Smooth grill, ie the US spec one. Basically the same as ours but without the number plate plinth.
Obviously you'd fit a number plate in line with the law, but for show purposes it's a nice clean look. Also a variation of that is to fit a 3/4 size number plate. Again, probably not strictly road legal so only for shows
Same deal with pressed plates, although I think there are a couple of companies that make road legal ones.
Oh, and that's reminded me... a 'DUB' number plate. Always fancied one, but I don't know if they're a bit of a cliché...?
