I have just the sport package on my A4 but kind of like the ultrasport trunk lip and roof antenna fin. I wanted to vinyl wrap my roof to give it the panoramic sunroof effect, but also wanted to add the roof fin as well. Should I: get the antenna fin the color of my car, or get a black one to blend in with the black gloss roof vinyl, also should I apply the fin after or before the vinyl? What is everyones opinion, my car is dolphin grey so if I do the black vinyl roof would the dolphin grey antenna look weird or should I just stick with black to blend in with the black gloss vinyl? Thanks
