This book is awesome.
More than 1600 pages full of data.
There are all the makers that ever built a single car in the USA.
Do you know that there was a Porsche from Massachusetts in 1905?
For the biggest makers, there are the general info about the marque and technical details of the cars, year-by-year production, with a chart containing 'ballpark' pricing informations, factory price and lot more.
For the others, the stpry of the marque, the list of all the models and the value, or just few lines in case of obscure ones.
The index is divided by type ( 4 pages with 5 columns each page containing Alternative power cars, Cyclecars, Highwheeler) and by country (17 pages 5-columns!).
Absolutely huge, the final reference about American cars.
The paper and the pictures are not of the highest quality.
