There's definitely location/cultural variety here, people would worry a white car wouldn't sell, due to the increased visibility of dirt and scratches, so only gets 5% of sales here. The top colours here are silver (24%), black (22%) and blue (17%, mostly darker shades).
I'm not sure why silver cars escape the stigma of white cars here since they have the same issues, but they do.
After the size of vehicles and number of pickups, the amount of white cars was the next thing that stood out to me about the cars when I first went to california
