I think I may have a new favorite page on the Internet: Diagnostic Sounds is a collection of sounds from John Muir’s How to Keep Your Volkswagen Alive VW Engine Sounds, a cassette companion to his seminal book.

John Muir is a hero of mine—you can tell by the number of times I’ve mentioned his book over the years—and if I ever invest in a vintage VW Beetle, it will be because of his book. And, now, his cassette.
