Not seen a LR3 off-road yet, they're all a bit too 'shiny' still over here for any people to risk them.
Depends a lot on what sort of off road you're talking about too - deep fording in a modern, electric everything, rover is a recipe for disaster if you ask me, but a reasonably set up (read as snorkel and extended breather kit) diesel powered defender can go as deep as the driver can take, provided he doesn't mind getting wet, cold, muddy and short on air
I prefer to drive my cars, rather than let the car do the thinking for me - but then I'm slightly biased as my signature line will show
Cheers,
