Car show class help

[PDW HOTRODS]

I am in charge of a car show, and I was thinking of adding a class, but I am not sure what to call it. A lot of people are getting barn find's, and old hot rods on the road, and people are making new ones look old. So I wanted to have a class for them so they dont compete against new high doller builds. I think rat rod makes a car sound low quality and poorly built. I was thinking maybe old school, or somthing like that. What would you call a well built hot rod that was built to look like it was built 40 years ago. Thanks. By the way, I am just a car guy, not a promotor. All the money made goes to charity and scholorships.
