LOL - I know what off-road means and what it doesn't more than most.
I drove *my* D90 in Four Wheelers Top Truck Challenge. I've been on my back, under my truck, replacing broken front axles from rock crawling, in the field, at 1:00 AM. (think empty axle/differential housing, disassemble hub and brakes, lots of parts that should fit back together again, a flashlight and dirt) I've spent hours winching through 4 foot snow drifts, wheels literally inches from from 100ft+ cliffs. Delivered mail to the hermit like types living in the remote box canyons of the Panimint Mountains near Death Valley. I've forded streams deep enough to have water coming out of gap between the hood and body of my truck. I have driven most of the hardcore and less Moab and Sierra, and S. California trails, along with a smattering of Oregon, Nevada and Colorado options.
Yeah this was few years back, late 90s and then into mid 00s, until my job took me to the east coast for a while. But I'm not that senile yet as to confuse parking lots with off-road. I'm not that stupid as to imagine doing the same in my LX570 as my very modded defender. But in the LX I have forded a large, 2+ foot deep, rocky creek crossing, managed to take out a sidewall on rocky fire roads, driven 10's of miles on unmaintained, winter run-off damaged fire-roads, needed four wheel low to get through a large snow bank to a campsite, completely cross axled the LX getting to a shooting range far off the road on BLM land, etc. and I've owned the LX for only about 6 months. In addition to the D90, over the years I've also owned, and off-roaded, a Jeep Cherokee (classic), Jeep Wrangler, Jeep Grand Cherokee, an FJ80 and a Ford E350 4x4 Sportsmobile Camper conversions.
Now, let me hear about your personal experience in your LX570, or similar vehicle, and/or some of your background driving other 4x4s, that might suggest that your comments on the LX570 and its capabilies are at all informed by any expertise or experience?
