Flyboy, your knowledge of English car makes is not as good as you think.
Land Rover who make Range Rover, Discovery, Freelander and Defender is a COMPLETELY different company to MG Rover who make the majority of the Rover cars in England. The two companies split years ago.
MG Rover is the originial Morris Garages Brand famous for the Morris Minor, MGB and a whole host of other classic English Marques, oh yeah, and not forgetting the Mini which unfortunately was the only piece of Rover that BMW kept.
