"Oh Shit" moments...

Ah I misunderstood. But even the Mk1 New Mini wasn't a Rover design 'through and through' - it wasn't really a Rover design at all. Rover developed some concepts (Evolution, Revolution, Spiritual) in the mid-late 90s but Rover design and engineering became less and less prevalent until eventually the whole project was taken over by BMW in the late 90s - the whole concept was by BMW, the styling was by Frank Stephenson at BMW, and the componentry was from BMW. The total sum of the British efforts in that car is the packaging of German components within a German bodyshell.

Again incorrect,

While BMW owned Rover at the time and ploughed their money into the project knowing full well they would be shot of Rover (minus the Mini) as soon as the Mini was ready, it is a Rover design. The components are not BMW, it's got Rover stamped all over it. Rover drivetrain, Rover sourced Chrysler engine from S.America, it was introduced as the new Rover Mini before BMW sold off Rover and kept Mini. The original design even had a K Series in it, it was a BMW boss that told them where to stick their K Series after the head gasket debacle.

I don't know where you're getting your info from...
