The Willys Aero Survival Count is a registry of Aero passenger cars built by Willys-Overland and Willys Motors (a division of Kaiser-Willys) from 1952 to 1955 in Toledo, Ohio, USA and from 1960 to 1971 by Willys do Brasil and Ford in Sao Paulo, Brazil. The late Bill Raub began to keep track of Aeros sometime in the 1960's. This project picked up where Bill left off and was begun by Rick Kamen in 1981 and documents every reported Willys Aero, whether it is restored, awaiting restoration, a driver, some hulk rusting away in a field or already scrapped. As of the latest update, approximately 1100 Aeros are accounted for in the United States (including Alaska and Hawaii), Canada, Brazil, Finland, Sweden, Europe, Israel, South Africa, Australia and New Zealand.

A database is kept of all pertinent information, such as serial numbers, trim and paint codes, engine numbers, options, past owners, and any other facts or photos volunteered by the owner. Through the registry, many unknown codes have been identified, production figures deduced and model differences discovered.
