Founded in 1951, the AOC caters for owners of all Alvis cars, even including military vehicles. You do not have to be an owner to join, associate members are welcome.

There are some 1,700 members world wide, in six UK sections (Scottish, Northern, Midland, East Anglian, South Eastern, Welsh and South Western), plus active overseas sections in the Netherlands, Sweden, Denmark, Germany, Switzerland and North America.

Stated objectives of the Club are the preservation of Alvis vehicles, the running of social and competitive events for all Alvis vehicle enthusiasts, and, in so far as is practicable, to provide services to members.
