In 1919, the small English firm of AC Cars came out with a new engine which, amazingly, was to power their products for more than 40 years. This is the first ever book devoted exclusively to the six-cylinder AC cars.The history of the cars in competition is studied, and the author also advises on the practicalities of owning any of these models today, including common problems, parts availability, maintenance and preservation.With its in-depth examination of these desirable ACs, this book provides an unrivalled store of knowledge for the many owners and enthusiasts who care passionately about them, and serves as a tribute to the men who made them.
