The spindle grille looks really good on the IS 350F in Black as you can see a pic of mine below. I used to hate the grille but it has grown on me especially since the car drives incredibly well with a nice sporty edge while still being very plush and comfortable.
As for Acura. The last really good looking car they made was my 2007 TL Type S (see attached). I really miss that car and I miss that Acura. If only Acura would have updated this chassis a bit, offered it as rear wheel drive and slapped a turbo on it, I would have never switched to Lexus.
