Other hobbies with these economics?

Audio seems to have an interesting set of economics for the consumer. Items depreciate substantially the minute they "drive off the lot", but remain just as "valuable" for many, many years in most cases. With proper care, these components retain basically 100% of their performance and usefulness, even with daily use. Compared to autos, computers, boats, etc., a well-cared-for used audio component is just as valuable, but much cheaper, than a new copy of the same thing.

Are there other hobbies where this relationship holds up?
