> If anyone has any recommendations I'd love to hear them

For kids: Just William (read by Martin Jarvis) and PG Wodehouse Wooster books (don't recall who read that).

Early Eddie Izzard shows were also memorably good as audio. Very quotable.

There's a gigantic, not always unofficial, archive of Just a Minute online, which is excellent car journey material. This is the first 5 series, but there's 80-plus series of it in total https://archive.org/details/Just-A-Minute

I absolutely loved those just william cassettes as a kid! Completely forgot they existed, must have been lost or broken. Will definitely be repurchasing
