They weren't.
I think there have been alot of people out there evangelizing the "greatness" of the XJ lately. Jason Camissa, Doug Demuro, Dex, Uncle Tony's Garage and a bunch of others. If you were looking a Jeep content, the Youtube algorythm would take you there. For a long time they were way cheaper than YJs/TJs. The unibody construction was pretty innovative in it's time and I enjoyed driving them when they were new. Where you could find one in really good shape 7 or 8 years ago for $3000 and rough ones for $800, it seems too many are chasing too few of them and those days are gone.
They're one of the few crossover SUVs with a solid front axle and are pretty easy to mod as a result. One advantage was that people did not tend to mod them until the prices dipped, so you could find nice clean ones, at least out west. The paint would fade, but the rust isn't bad. ZJs and WJs are out there too and a WJ 4.0L shares the motor mount layout with the TJ. I considered buying a high mileage running WJ as a donor for a stroker build, but it doesn't make financial sense either.
My brother in law has one of the last 2 years of production of the XJ Cherokee in excellent stock condition and he takes as much joy from owning it as most of us do from our TJs. I think he may have bought it new. They definitely have their fans.
Don't get me wrong I loved mine and still do love them, just not for the price they command. The driving experience is not worth the price, IMO. They are cool and definitely have their place, but 10k for one with high mileage and basically every wear component needing replacing is not worth it. I grew up in the back seat of an XJ, and was a member of NAXJA for 12+ years. The XJ was built as an economy vehicle, and it drives like one. While I'll agree with the other posts that a ZJ/WJ can be an electrical nightmare, at least they drive a lot nicer. They were "expensive and hard to find" back when I bought my last 2000 XJ with 76k miles for $6000, and that was in 2009.
