The Clube de Automóveis Antigos da Costa Azul (CAACA) is a nonprofit association in Portugal dedicated to promoting and preserving historic automobiles. Founded in 1994, it grew from the need for owners of classic cars in the region to connect, cooperate and support the appreciation of automotive heritage. The club brings together a community of enthusiasts and offers members access to advantageous insurance conditions for historic vehicles, along with assistance in obtaining official vehicle certification.

CAACA also organizes a varied calendar of activities, including classic-car outings, historical tours, parades and exhibitions. Events such as the Costa da Caparica Classics and the traditional Passeio “Ribeirinho” give participants opportunities to enjoy their vehicles, explore local destinations and share their interest with fellow members. The club’s website features event information, announcements, a calendar and a photo gallery, helping members and visitors stay informed and involved. With hundreds of members and a long record of activities and events, CAACA serves as a meeting point for those who value the history and preservation of classic automobiles.
