The Clube Aveirense de Automóveis Antigos (CAAA) is an association in Aveiro, Portugal, dedicated to historic cars and motorcycles. Founded in 1991 by 20 members, it brings together enthusiasts to promote the preservation of the country’s motoring heritage. With more than 600 members, the club supports collectors through guidance and benefits related to acquiring, restoring and maintaining historic vehicles, as well as access to specialist documentation, collections on display, talks and club facilities. Members can also access economical insurance for eligible classic vehicles and take part in the club’s events.

A central part of CAAA’s work is Automobilia, its internationally recognised transport-collecting fair, held at AveiroExpo. The 2026 edition is scheduled for 22–24 May and will feature more than 300 exhibitors offering vehicles, parts, tools, technical documents, memorabilia and miniatures, alongside themed exhibitions and activities. These include gatherings and drives for classic cars and motorcycles, an antique-bicycle ride and journeys on vintage buses.
