FJ's have actually legit stopped depreciating, and in most cases have actually appreciated. They are few and far between, and in high demand by enthusiasts, which drives the price up. It would actually be a good model for Toyota to update and start producing again. They stopped making it because they figured there wasn't much of a market for it, but given that a lot of manufacturers are starting to release specialized vehicles like this (the Colorado ZR2, Ford Bronco, Wrangler, even the 4Runner TRD PRO), there is obviously a growing demand for adventure vehicles like this.
