Dennis and Alexander both grew separately. Dennis was very much a specialist chassis builder with a list of regular customers, while Alexander’s roots were in building bodies for a group of Scottish bus companies. Alexander broadened its customer base from the 1950s and was soon supplying bodies for bus operators throughout the UK and in several export markets. Dennis expanded dramatically in the 1980s with its best-selling Dart model. Since the two companies came together as Alexander Dennis Ltd in 2004, it has concentrated on designing and building a range of best-selling bus models. The coachbuilder Plaxton, established in 1907, joined Alexander Dennis in 2007, mainly producing coaches, but doubling up with Falkirk to produce the bus range. Alexander Dennis is one of the very few manufacturers building buses in the United Kingdom. With over 180 images, this book provides the history of the company and its subsequent emergence as a clear market leader.
