I think that at some point, the different between an old car and a new car was bigger than others. Like the different between something from the 30s and 50s (I'm guessing) wasn't that huge. It's not like you went from points to electronic ignition or carbs to FI, fancy radios, electronics, etc... What about the 50s to 70s. Did most cars in the 50s have AC? What about in the 70s? When did AC become de rigueur, 60s, 70s, 80s or 90s. I can't imagine a new car that doesn't have AC, or is that just regional?

So, in what 20 year period did we see the biggest change in the technology (convenience, comfort, reliability) in cars, 50s-70s or 60s-80s or 70s-90s?
