Buick drivers can't see IN FRONT OF THEM, let alone, in a rear view mirror. (They find the cruise-control by feel)
Bucks are known to stop in all Rotary intersections.
"Happiness is Lubbock, Texas, in my rear view mirror."
I had a Buick once which had a rear view mirror...never drove it near Lubbock, though.
