Spent some time with the color in different lights. You will find it has subtle blue and purple undertones that make it much less borning than a brilliant silver or other bright metallic silver. Also keep in mind that Avus is a pearl not metallic.

In direct bright sunlight Avus looks one color, in indirect another, in shadow/shade yet another.

Parked alone it might look like a borning silver car, but parked next to one of the 9 million bright silver metallic paints out there it really stands out and looks closer to a grey.
