I bought a wd21 partly for the price (hard to beat $900, even with a few problems) and partly because of the lack of rust and body damage. But mostly I didn't want a newer car or something that's too common. I was actually looking at an even more rare vehicle (daihatsu rocky anyone?) but it didn't work out and I didn't want to have driven to Arizona for nothing. The 2000 Mitsubishi montero sport I had before was crap, IMHO, so I don't like all Japanese cars, but I have become a fan of Nissan since I got a pathy.
My dad is a hardcore Mopar man. He always had mid 80s Ramchargers when I was growing up, and now he has a chrysler 300m and a '76 plymouth trailduster (!!!). He never liked foreign cars until I got my pathfinder, but my wd21 has him convinced. He gets frustrated helping me with the 33 swap, since everything is packed in pretty tight, but I explained that in order to get full blown 4x4 in such a small platform they had to make hard decisions like making us take out the front diff to get the oil pan off.
I got rear ended a while back and it totally destroyed the new "SUV" that hit me, and I only had a couple dents, a smashed tail light, and a bent tail pipe. The insurance company, in their infinite wisdom, decided to repair that POS because it's "worth more" and totaled my truck because they don't think the whole vehicle is worth the price of a paint job. I told them flat out they could have my Pathfinder over my dead body and they cut me a check for $5000 and said I'd have to retitle it as a "salvage vehicle". They also said that there was "nothing special" about the WD21 and they "aren't collectable". I went off on that lady, though I kept my language clean. I told her that I was a member of a group of collectors (you guys) and if it was nothing special then why did it hold up so well to a fancy new car that weighs like half again as much.
Bottom line: I bought it because I could afford it and it had the 4x4 I needed, living in rural Arkansas, and I kept it because it's awesome. If I somehow became rich I'd still keep it. I plan on driving that truck (or another wd21 if anything serious happens to it) for the rest of my life. Plus I like not having a Ford, Chevy, or Jeep which is all people around here seem to buy. My ex had a grand Cherokee and I hated it.
