The Fiat 1800 and 2100 (and later the 2300) represent the flagship models the Turin-based firm offered in the mid-Sixties to a clientele looking for a large, elegant, robust and reliable car at a price undercutting the contemporary Lancias and Alfa Romeos. Along with the classic saloon versions, a modern station-wagon and a ceremonial long-wheelbase variant were also offered. They were all powered by a refined straight-six. The range was extended in 1961 with the splendid and powerful 2300 S Coupé bodied by Ghia, one of the most successful and attractive Fiat sports cars, while the following year it was the turn of the more economical four-cylinder 1500 L. This book tells the story of the birth and development of this significant family of Fiat cars, presenting the technical issues and historical details of the various versions produced. Equipped with detailed technical files and illustrated with numerous contemporary images, the book also provides a very useful guide to restoration and invaluable maintenance tips.
