What happened was LR did some genetic engineering, and went from a medieval courser to a Viszla overnight. They didn't have the resources to gradually evolve it while they focused on the volume sellers. You can look at the Range Rover and no one would say the current one isn't true to and a clear evolution of the original.
Criticize 1997 Land Rover for not evolving the Defender, but 2020 Land Rover corrected that oversight. Ironically, had they not gone off and done the Evoque, they would be just another brand in the dustbin of history right now.
I may have never mentioned it here but I have been always critical to the original LRD especially for unwillingness to bring changes, the evolutionary changes, and address the quality issues.
Past early 90s LR did actually stop caring about the Def it ended up at the mercy of the aftermarket. By this time LR had become a joke in terms of built quality.
And yes you right they suddenly gave us a new vehicle after had been ignoring it for 20+ years.
Is it a great vehicle what they gave us? Yes it is. (I wrote about it a few pages behind). It is a great vehicle for the purpose they think is not longer supposed to be the original. (my personal opinion)
Would I ever buy it? Yes, if I could afford it and also being able to find a strip down version with tow and offroad package. (as utilitarian as it is available in the US market)
When I do find, would I ever drive it to say form the lower 48 to all they way to Alaska or Hudson bay or Labrador? Yes, maybe, I was stupid enough to drive my Saab on the BLM roads in MT, Idaho and Nevada.
