This even works for some non-antique cars. Jeep Wranglers (TJ generation) and Mazda Miatas (NA generation) have both appreciated somewhat in recent years.

Of course, no one's getting rich when a car appreciates from $5000 to $6000 or $3000 to $3500 over a few years. Net of repairs it's probably break-even. But it's nicer than losing value :)
