In case you have been living at the bottom of a well or something and haven't heard about it.
Rusty Ironmongers is a Facebook group reposting ads of vehicles that ought to be saved. The usual selection is asking price under $1000, older than 1970 (exceptions for cool stuff), and ads with pictures because everyone likes to look at pictures of old cars and trucks.
If you've got Facebook you can join up and troll your local Craigslist to see what you can add to the mix. Tell anyone you think might be interested. Especially if they're a rich, eccentric car nut.
