Help - To buy or not to buy

[Portland68]

Hey everyone, my dad and I are looking at this truck and are trying to figure out if it is worth the money (and what it is worth if we don't hang on to it, can't be upside on it before buying), we were hoping for some advice.

The truck is a true Cheyenne Super (check out the SPID, "Cheyenne Super Sport"...there was a thread about this a while back, just some inconsistent records from the factory), very low optioned truck, has rust in the rockers, and these are the only pictures I have of it so far. Motor is a 383 stroker and it "runs and drives"

1) Is it worth the $1,500 asking price
2) How much is it even worth? There's a ton of missing pieces but it is a true super, if it were any other truck in my area I'd go $800 on it but let me know what you think
