I remember my dad's new 1963 Oldsmobile. He had to special order seat belts. They were not mandatory for a few more years. The radio was AM only. FM was an option. No head rests, drum brakes, mechanical distributor and a completely metal dashboard.
I believe I still felt safer driving that old Olds back in the 60's.
Do you happen to remember if the Olds was a 88 or 98? An 88 was the last demonstrator that my dad had as he died just as the 64's were coming out in the fall of '63. Our demonstrators had had seat belts for several years before that. Dad was very high on their use. So when I bought a '58 Chevy Delray with nothing on it a year or so later I really missed using them. So I had them added.
