PJ around here, D90 means D90. The D90 is in no way coming back to the US. New Land Rover model? -Yeah, one day. Defender 90? No way.
Don't worry your truck will retain most of its value as long as you don't let it rust into the ground or bash it too badly against rocks and trees
It would be expensive, but it is possible that LR could equip say 200 "Gold Edition" or whatever they wanted to call them. And bring them to the US for a last hurrah. They'd be 100k each, they'd sell out in a month, and I'm sure we'd get the biggest bunch of mixed up mish-mash parts, basically whatever they have clogging up their warehouses. But don't hold your breath for it.
"Yeah, make sure its a flatbed...."
