Interesting question Kaj.
So here’s another similar situation I just came upon.
My brother-in-law saw a 968 cab in western Washington last week that he says is Violet Blue.
According to records (thank you Jeff) there was only one Violet Blue cab made, and Carfax shows it residing in Maryland somewhere which is waaaaayyy across the country from western WA.
Jeff did note that there is a rumor that one of the Paint to Sample cabs was Violet Blue, but I guess that’s not confirmed.
So, assuming the car my BIL saw was indeed Violet Blue, what car did he see, the Paint to Sample Cab?
