ACOC registers do not record information readily available in commercially-published material (for example ‘Original AC Ace & Cobra – The Restorers Guide’ (Motorbooks International)).
They serve to record, for individual cars, material known facts that might not otherwise be made available to potential owners.
The conclusion that ‘the registry is a little vague’ is not one I’ve heard before, from either oldies or newbies. To the contrary, most users seriously interested in an individual car are surprised by the quantity of information that supports individual entries. For example, the Thames Ditton Cobra Register is 480kb; only 770mb (less than 0.2%) is published on the Club’s website.
