aaaaand introducing myself as well.
I'm Ron, just about to take delivery of our new Zermatt Silver 2015 Interstate Gran Tour.
We chose silver because I'm a motorsport nerd.
Until the 1960's, auto racing teams, such as Formula One teams, used national colours instead of sponsor livery.
American teams used blue (Imperial Blue, not ironically)
British teams used British Racing Green
etc etc...
German teams used silver, and as the Interstate is at it's core, a Mercedes....
Silver it is.
