Thanks for the comments, guys!
I've just been thinking about the sound on my Dad's old Cadillac back in the seventies. Okay, the thing was a beast, like a tank that floated on marshmallows, but with all the sound-dampening put in it, you never heard the motor more than a faint distant purr. Between the plush uphostery, thick shag carpet and the padded headliner, there wasn't much other than window glass to reflect sound. While far from ideal, you could have done worse for a "listening chamber".
It had cassette deck, radio, 8-track(!) and if memory serves me right, two 6" x 9" speakers on the back deck and two (perhaps slightly smaller?) in the front dash. Not true audiophile, but really not so bad, either. With the windows up, you could hear MUSIC.

When the car came from the dealer, they even threw in a few free 8-tracks, including a classical music sampler and Barry Manilow!

Led Zep cranked up nicely in that car, but the dealer didn't give that one for free. Guess they had ideas about their target market's tastes!
Not really true audiophile, but not all that bad, either. Good enough you could genuinely "enjoy the sound" as you cruised down the road. You could hear some bass, some midrange, and some treble -some detail and a sense of soundstage, even if it was sort of swirling all around you.
In contrast, all I could hear on my friend's new system the other night was... thin, ugly somewhat sibilant semi-treble.
I think when I finally do go back to owning a car, I'll go vintage inside it, too... unless maybe I get a deal on one of those McIntosh's! :scratch2:
