My how times have changed. I remember adverts for older cars from the 1970s, usually British, and one of the acronyms in the for sale listings was R&H meaning "radio and heater". Yes, these were not standard.
Today, I cannot think of a car without climate control, rear window defogger, some kind of radio, and more air bags than one even knows about.
There are still a few um, "thrifty" people, namely in Alaska and Vermont (I know this from friends in the industry) that would still love roll up windows and no a/c...and are incensed when they find out that like it or not, they cannot get a car like that!
And lately I've been taking very long trips to see my father, who turns 102 on Friday. This involves 14 hour drives on our interstates. It's astounding to me how many drive on the highways at 70+ MPH with all their windows open. I'd go deaf. I guess their a/c doesn't work or they think they are saving gas.
