Hi guys - I'm very interested in ordering a custom A6 or A7. I saw an article that said it was unclear if the Air Suspension and 4 Tire Steering options would come to the U.S. market in the A6, and that perhaps those would only be available in the U.S. in the A7, if at all. Anyone know? In looking at some sheets my dealer printed, I do not see such options listed for either car. Then again, this printout may not be comprehensive. For instance, I do not see a Black Optics package listed for either car in the printout either. Anyone know if that'll be offered? I know its available at least in Europe because I saw a gorgeous black 2019 A6 on YouTube that had the black grills - looked AMAZING!
