@zephasaurus_hex @lapis I read a handful of the Hardy Boys books as a kid, mostly the (what I later discovered were revised) ones from early in the series. The only one that sticks in my mind, though, was one from the 80s that had them get involved in astronaut training for the space shuttle or maybe just space camp.
That and I learned the word “jalopy” which was always applied to Chet’s car.
