When I think of "off-roading" I'm thinking mud, muddy water, etc, and there's no way I'm doing that to a 75-100k plus vehicle that relies on a shit ton of electronics to simply start.
I do all those things in my LR3, which relies on a shit ton of electronics. I've had it submerged to the tops of the wheel arches, belly deep in mud, rock crawling in the desert, and creeping through the technical, twisty trails in the Cascades. Granted, it's worth maybe $8,000 if I'm lucky, but the point is I am not alone in pushing a modern, electronically complex vehicle hard in difficult - and remote - terrain. And I'd do the same in a brand new Defender or Grenadier. These things are not precious, they are tools to be used for a purpose.
And just because my LR3 isn't worth much doesn't mean I abuse it. I take good care of that vehicle and try hard to avoid damage. So far, so good.
