You don't often see an LX getting really down and dirty like that, so it was fun to watch. With a body kit to fix the approach/departure angles back to Land Cruiser spec and taller tires it'd be quite a formidable off-roader.
Off-road SUV, your can count them on your fingers:
Toyota Land Cruiser (200 and 70) / Lexus LX
Land Rover LR4 and Range Rover Vogue
Mercedes G Class
The Toyota/Lexus are the most complete ones, the 'best' at everything. Land Rover and Range Rover could be better, but their bad reliability is just not acceptable. Jeep Wrangler is too hard-core, and even not noticeably more capable if not modified. The G Class has the most potential, but lacks Toyota reliability and Range Rover luxury.
Mercedes could have made a nice LX rival, with the M Class, but that car is just not as capable, again again not as reliable as desired.
I want Toyota/Lexus to even further improve their car with the next generation. Toyota could steal a huge market of they themselves built armored Land Cruiser and designed their car with armoring in mind. All armored Land Cruisers are built by third parties, and factory armoring is better. See Mercedes Guard.
Indeed, Lexus LX and Toyota Landcruiser are the most well rounded offroad vehicles. My family first Land Cruiser, LC80 is still running well after 20 years owning it. Proud to be Toyota and Lexus owner (2012 Lexus RX)
