Hi all- my first post here on Audizine, just picked up an A3 Premium plus. I want to change up the grille: does anyone know the difference between the "A3 S-Line black optic grille" and the "S3 black optic grille"? Besides the S3 badge obviously..

I'm looking at this http://europrice.us/grille-a3-s-line-black-optic vs http://europrice.us/grille-s3-black-optic and trying to find out why there's a huge discrepancy in price. I believe the part #s are 8V5853651DCKA and 8V5853651BCKA but not sure.

Any help would be appreciated!
