Ever since its first launch in 1989, the Land Rover Discovery has stood for robust durability and practicality both off and on-road. When the Discovery 3 was launched in 2004, it represented a step-change from the earlier models, with much higher levels of equipment and a greater degree of luxury as well. The Discovery 4 continued the same theme, with additional improvements and refinements. Rover expert James Taylor examines the background and development of the L319 platform, common to both models, and the different types within each range. The book also covers the G4 Challenge vehicles and special editions, as well as emergency vehicles, armoured derivatives, and the US models that were known as the LR3 and LR4. Including a wide range of colour photographs, this is an essential guide to two Discovery models that are widely regarded as some of the best SUVs in the world.
