I believe Land Rover SHOULD have built a
Grenadier type replacement, in fact they could have most likely used the original Defender pressings so it would have looked even more like the original.
However their market has become luxury vehicles and the "Defender" that they have built is designed for that market. lt's selling extremely well despite large price hikes.
So Land Rover would say it's a success. l
don't doubt that if they'd made a "a Grenadier" it would have also sold very well, but they probably don't want the Utility image any more.
Look at it this way, you now have a choice, new Defender or Grenadier (or keep your old one) and that's got to be a good thing.
Personally l love the look of the Grenadier, and plan to order one. l currently have a new Defender having traded my 2005 110 TD5 after 90,000 miles in eight years of ownership.
