What are these worth?

I have been looking for another old Mopar. I posted a thread on a real nice '65 Coronet 4-door for sale but it sold. I still really like the '65 Chryslers. I found this 300 two-door hardtop about an hours drive. I e-mailed the seller and he sent me some more pics and info.

Definetly needs some TLC. but everything seems minor. Some surface rust but nothing major. I really like these bodys and interiors. I drove a '65 Newyorker last year and thought it was great. Says the price is negotiable. What do these typically go for? Is there a vendor or website of some sort that sells parts for these cars? Ebay was all I could think of. I know the C-bodys are the least desirable Mopars maybe thats why its tough to get parts. Just thought I would get second opinions before I go check it out in person. Hope I posted this in the right thread, if not can it be moved. Thanks

Thanks everyone for any helpful info.
