Model T Fords are still de rigeur in Toledo? You can have any colour, as long as it is black. Black doesn't work in Australia. You know it's summer when the steering wheel is too hot to hold, and a seat belt buckle becomes a pretty good branding iron - and that's in a white car.
I think red is the favorite, but many people will not buy a red car. There a few untruths out there about red cars but I loved my red car, myself. I also loved my blue car. My tan, gray and gray/brown cars I did not love. I will buy a car in a few years and it will be a red or blue SUV.
Under sodium vapour lamps, red turns exactly the same shade of grey as the asphalt it's on. I've owned a red vehicle but never felt entirely safe in it at night - it was practically invisible.
White seems to be a favorite with many people. I'd like to have a vehicle that makes me look good with my gray hair. Probably blue: the new blue that came out recently.
