Manhattan Grey, black optics, Cavo 19" wheels and replaced my A7. Hadn't driven the S5 Sportback (ordered from early production run), just the S4 Avant and S5 Coupé. The Coupé has a shorter wheelbase than the others, and feels more pointy/darty/loose/agile (pick the adjective that suits your lexicon) as a result. The Sportback feels more like the S4, but the difference is relatively subtle.
Black optics will eventually turn up in NA. It was not originally available in my market, and appeared on the order system the day I went in to confirm. So it is hard to predict when it will appear. Was considering Navarra Blue initially, and black optics not such a good fit there.
