My favorite car, a 1967 AMC Rambler Rebel (pretty much the same model as the Ambassador) named Hezekiah had an 8-track. I think I had Best of Bill Withers and a Greatest Hits thing from War ("Low Rider" etc.). Great car, commuted over a hundred miles a day with almost no troubles.
I tend to like old beaters, muscle cars, really. I like bench seats and four hundred horsepower. I do not like computers in cars. I like cars I may have some chance of fixing, as I do have a tendency to get stranded a hundred miles from anywhere. I've driven new cars and trucks - basically don't like 'em. Almost all have the "Service Engine Immediately" light on, and 90% of the time it's from clogged oxygen sensors ($400 each, if you're lucky, and they have almost nothing to do with the operation of the vehicle).
To get to basics, I listen to the radio almost exclusively when in the car. I use an AM radio at home, just for baseball games. (I've listened to games on the radio all my life, do audio-only is natural and I can easily envision the game even if there are other things going on.) It's also a time I can listen to music LOUD. Yah, still an old rocker. Three buttons for local classic rock stations, one for eclectic rock (KBCO) and one for the all-comedy station (for when all the rock stations go to commercial at the same time), No CD or tape or plug-ins or nothing. Just a potent enough radio to draw in a signal if up in the mountains stranded or whatever.
(I had the 4-door sedan, with seats that laid down flat to form a really uncomfortable bed.)
I also spin the dial often enough to sample other genres. I watch stuff on TV. I'm old and have preferences, but thank the good Lord that I remain open to new stuff! I hated it when I was kid and anything that wasn't sterilized Big Band was "junk" and I was going to be punished for listening to it. Instead, I've kept an open ear as much as possible, despite disco and rap falling in there at times!
