Book excerpt: The W114 and W115 models were enormously successful for Mercedes-Benz, and their sales in nine years of production between 1967 and 1976 almost equalled the total of all Mercedes passenger models built in the 23 years between 1945 and the time of their introduction in 1968. There were many reasons for this success, but perhaps the most important was that Mercedes expanded the range to include a simply vast amount of variants including four-cylinder and six-cylinder petrol engines, four-cylinder diesels; saloons, coupes and long-wheelbase models. With around 200 photographs, this book features the story of the design and development of the W114 and W115 ranges. It gives full technical specifications, including paint and interior trim choices; includes a chapter on the special US variants; gives production tables and model type codes and explores the Experimental Safety Vehicles developed from these cars. Finally, there is a chapter on buying and owning a 114- or 115-series Mercedes.
