Well, l was wrong with that statement because despite LR's efforts the Grenadier is alive and well.
I was going to buy one but couldn't get delivery before March 2023 (when a govt tax incentive on commercial vehicles ends)
l ended up with one of the new "Defenders"
Although it's nothing like the old one, it's a very good vehicle and in base 90 Commercial spec with the steel wheels it does at least look something like a Defender.
