🏷️ Basic Information Identification Make: Land Rover Model: Discovery Year: 2001 Codes Chassis Code: L322 (Second Generation) 👋 Introduction Market Position Market Position: Premium SUV, competing with vehicles like the Toyota Land Cruiser, Lexus LX, Mercedes-Benz ML-Class, and BMW X5 of its era. Known for off-road capability and luxury appointments. Competitive Analysis Competitive Analysis: The 2001 Discovery, part of the L322 generation, represented a significant shift towards a more integrated chassis and monocoque construction (though often referred to as integrated body-frame), moving away from its earlier body-on-frame designs. This brought improved on-road manners while retaining substantial off-road prowess.
