Yes things do break down. They still sell CD players. Scamazon has many portable ones including Sony. I bought my main home CD player art worst buy ( magnolia).

I recently bought a portable CD player that outputs a FM signal. So I can play my CDs on the radio now. Which can replace a car CD player. Studebaker brand.

But IDK about new car audio with a CD player. A quick look at Crutchfield shows they do still sell CD players and DVD players.
