At least around me, there's a good number for sale. Lots more if you don't mind water cooling and/or subaru engine swaps.
Mostly parts are available; although some things need creativity: federal EGR filters are unobtainable so people might EGR delete instead, rear side markers aren't available, so you have to use Mercedes G-Wagon parts (but they used to use Vanagon parts and scratch off the logos!), I had to adapt a crankcase ventilation valve from a different car because they don't make the ones for mine anymore. Also, headlight switches are available new, but the molds are wrong, so they break when installing (I found a used one, and added headlight relays to reduce the current going through the switch). Oh, and I'm in the second year of ownership, so I started getting fun problems where it runs ok at home but not on the road.
When it is running though, you almost have to drive the snot out of it... Otherwise it'll take an hour to get up to speed.
