I don't think it was cut for cost savings, more than likely because it was not part of the design ethos behind the Grenadier..
Personally, I think you are missing the point of the Grenadier. Sir Jim's design criteria wasn't to build another luxury SUV, it was to build a capable utility with respectable load capacity for expedition and utility service. Daily driver capable, but not focused on daily driver amenities.
There has always been the question of whether there is a large enough market for this to support the brand. Land Rover clearly didn't care about it when redesigning the Defender, and I'm sure they are selling many more Defenders than if they had gone this route. The Merc G class and the NewFender would likely be much more to your liking, but built to cater to a different market.
Just because the Grenadier is cool looking, and people buy it because of how it looks or makes them look to others, doesn't change this. When the North American Spec Defender 90's came to this county in 1994, it seemed like every other driveway along PCH in Malibu had one in it. A year later, most were gone from those driveways, and for a few years, used D90's were easy to come by for decent prices. Point is that people bought them because they were cool, but when they realized they were street legal tractors, they didn't want them anymore.
There is probably a case to be made for offering a 'tarted up' Grenadier with luxury amenities to cater to the market that buys G Wagons and the like. As long as they keep the Utility focused models, I'm fine with that, but like others I crave a more 'basic'
truck, not a trendy SUV to be 'seen' in.
Heck, even the Grenadier has too much technology in it for me, but you can only get so far away from it in 2025 and still meet regulations..
EDIT: it was
designed with this type of use in mind, not for impressing rich friends, or being seen on Hollywood Boulevard..
