Fink the first Disco was on a RR chassis, but may be wrong.Lr did the same. After the success of the Freelander they based all future lr's on that. Independent suspension. Got rid of the rusty chassis in favour of a unibody construction. They even put a 2L 4 cylinder hengin int latest phev range rover anorl. Makes sense really. When yer gottid perfection yer can't do betterer so copy it.
