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
- Jeep Wrangler
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.
