Re: Why are they ending it now?
Probably becuse the space taken up by the line is needed for something else.
Bear in mind the Defender is basically hand made and so costs a fortune. I've been round the factory. The Range Rover is built by robots that glue and rivet the whole shell together and then some fiddly bits are added manually.
The Defender still has to have the alignment done on its headlamps.
The two lines are chalk and cheese. And yes, I fully expect production to restart somewhere cheaper.
