Classified ads are the heartbeat of any old-car hobby publication. The word ads (usually in the back of the book) list cars and trucks for sale, tools and equipment you need, restoration services, real estate . . . almost anything you can think of. Many dealers run multiple ads looking for cars they want to buy. There are events listings and car clubs. In Old Cars Weekly, the "Kenny's Klunker" ads for low-priced cars are always fun to look through. You never know what you'll find there.
Years ago, I had a friend who used to get a magazine with classified ads. He would only read the Buick ads, because he liked Buicks. Then he threw the magazine away as soon as he finished reading the Buick listings. That's what I call a real classified ads lover. He literally wasn't interested in anything else inside the magazine -- just the ads!
