I know this is an older thread, but wanted to reply because I have an Arrow Grey S5 Sportback and at one time (randomly) was parked right next to the same model in Nardo. In my opinion @bkkchris these two colors are very different. Arrow grey has a ton of variation in appearance based on setting, sky color, etc. it can go from looking almost white to a putty grey color. Nardo is darker and more brown.
My point is that while both colors are great, they are more than slightly different. I think Arrow Grey is an all time Audi color and get comments on it often, even though mine is 6 years old now.
