I did a bit of digging to see what I was missing. Perhaps I have seen Land Cruisers lately but didn't notice as they look almost exactly like the Sequoia to anyone not in the market researching both. Here is what I found about them that cleared things up for me.
"Toyota's two-vehicle, large-SUV strategy focuses on two very different buyers. Land Cruiser buyers are college-educated males and middle-aged, with a household income of $237,000. Almost half of them are married with children and use their SUV as a family hauler or for vacations.
Since its introduction, Sequoia had maintained one of the youngest buyers in the large-SUV segment with an average age of 40. It is a family hauler, since nearly 60 percent of Sequoia owners are married with children. They have an average household income of $106,000."
The differences I found in design are "neat" but with the prices they each run, atleast 99% will never see any more offroading in the US than cutting a corner too sharp and dropping the rear inside tire off the pavement. Pure status symbols for folks with deeper pockets than their neighbors---just as you posted about the guys with the Tesla stable mates for theirs. Seems like the solid rear axle and link suspension and a few other "upgrades" that could have been just been offered as a package on the Sequoia are about it. But that wouldn't be enough to stand out in the eyes of those one would be trying to impress. Sort of like a Suburban vs an Escalade. Very similar but one is at home at the country club while the other is typically bought for oilfield transport and soccer mom-ing about. I take no issue with someone buying a luxury vehicle at all. It is their money to spend as they like. We all like to have something we can show off. Living in S Fla where I constantly see 70-80 yo.s at the redlight next to me in the baddest AMG Merc, winged Vipers, 200 mph Astons, Jags, RuF Porsches you could imagine. In my neighbor hood there is an Excursion on ~54" military tires, an F150 baja pre-runner rig, 2-3 Raptors, a V10 RAm 1500, not even getting into all the race and muscle cars from the '60s. Only an "enthusiast" for certain marques could tell the difference about many vehicles though. Take a standard Mitsubishi vs an Evo rally car, or a commuter MB vs an AMG version of the same body, Expedition vs Navigator, Sequoia vs Lexus, vs Land Cruiser! It used to chap me when folks would ooh and aah over my "jeep" at a gas station. Couldn't those neophytes tell I was driving a '76 Ford Bronco!!! A jeep,,,INDEED!! LOL
With a 60-75K price tag you'd have a butt-load of money in price difference to throw at a Jeep Wrangler for upgrades. Wonder if that would be enuff to have a J8 imported or just have one built? If you couldn't spin your own wrenches a call to Bruiser's Conversions for a 4BT swap and some nice aftermarket axles with selectable lockers, skidplating, bumpers, and some conversion van company seats. Have a front cage upgrade done to up the safety level to rival the LC, opt for a set of nice 33" tires (about the biggest typically used on LCs) and call it done.
