An independent record
of the AC Aceca
Written and maintained by an enthusiast owner. Corrections and contributions are warmly welcomed.
About this site
This is an independent, accuracy-first record of the AC Aceca and Aceca-Bristol, hand-built at Thames Ditton in Surrey between 1954 and 1963. It is written and maintained by an enthusiast who owns an AC Aceca-Bristol, and has no commercial affiliation with AC Cars, the AC Owners' Club, or any dealer, auction house or restorer.
The intention is simple: to be the most useful reference on these cars that exists on the open web. Owners, prospective buyers, historians and the merely curious are all welcome — and if you spot something you believe is wrong, or you can add to what is recorded here, please get in touch. Contributions are how this archive gets better.
Our approach to sources
Every material fact on the site is checked against multiple sources — the AC Owners' Club register, contemporary road tests, marque specialists, published histories and, where possible, surviving works records. Where sources disagree — as they often do on production totals, exact power figures, or the fate of a particular chassis — the site says so, and shows the range of reported values, rather than silently picking one and presenting it as settled fact.
This is a small but important editorial choice. It means some pages read a little less tidily than a marketing site. It also means what you read here has been weighed, rather than copied.
Resources
A short list of the external resources most worth knowing about. Period road tests, auction house model histories, and marque specialists are the three most valuable primary sources for anyone researching an Aceca in depth.
AC Owners' Club
acownersclub.co.ukThe historic marque club for AC Cars owners. The Registrar holds the most complete continuous record of surviving chassis, and the club magazine and annual meets are indispensable to anyone researching an Aceca.
Period road tests
archive.org — AutocarContemporary reviews from Autocar, Motor, Autosport and Road & Track are the closest we have to a factory voice on how these cars drove when new. Reproduced digital archives are a valuable primary source for performance figures and spec quirks.
Auction house model histories
bonhams.com — AC Aceca resultsWell-researched catalogue entries from Bonhams, RM Sotheby's, Gooding & Company and Silverstone Auctions frequently uncover ownership histories, works records and chassis provenance not published elsewhere.
Marque specialists
acheritage.co.ukIndependent AC and Bristol specialists — restorers, engine builders and parts suppliers — carry decades of first-hand knowledge of what is correct, what has been changed and what is unobtainable. Their notes and workshop records are primary sources in their own right.
Bristol Owners' Club
bristolownersclub.orgThe natural sister club for anything concerning the Bristol two-litre engine used in the Aceca-Bristol. Their technical library and register are excellent for engine numbers and mechanical originality.
