Thanks for all the great advice guys. It's nice to hear folks holding me back down close to earth with everything. lol.
I paid $4000 for it. It was at $4700, but we came to an agreement. It does still have a USGS sticker on the window.
It does seem probably a bit high, but it is straight, rust free, and unmolested, which makes it worth it to me, especially after some other ones I looked at.
It does have AC, and was converted to R432 or whatever, but probably has a leak or something, it's very wimpy.
Seller claims the 64000 or so miles are original, it hasn't gone around the clock yet. It's hard for me to know. The pedals are always a good sign, they are old but not worn like a 164000 mile truck would be. But they aren't new either. There is an occasional puff of blue smoke at start up, so there's that. Who knows? Either way, the paint and dash are toast. It has obviously sat in the sun for a very long time.
Either way, it is a good foundation for me to build an exploration vehicle. I don't know anything about these TBI units at all, so I might be asking some dumb questions about those when the time comes.
But for now I'm very happy. The manual shift makes me grin like a fool every time I drive it.
