The current generation of the Dicovery/LR3 is 11 years old. For reference, at the time of its debut in 2004 the Toyota Tacoma was in its first generation, and so was the Ford Focus. You could also walk onto a dealer lot and purchase a brand-spanking new blob-eye Impreza, E46 BMW, or an Oldsmobile!
The Disco3 received numerous visual and mechanical updates over its life, and was even renamed LR4 to symbolize how far it’s come. But the chassis, body, some drivetrains, and interior remain basically the same.
Not that there’s a burning reason to change it. I think it still looks great and contemporary, though I prefer the unabashed upright-ness of the 2004, un-facelifted Disco. Keep on truckin’, mate!
