Value of a Fully Restored Chevy C10

[Coues106]

I've got an aunt and uncle who are getting on in years and have asked with help selling a 1965 Chevy C10 they had restored on a whim in 2019. I'll be the first to admit I don't know a whole lot about cars; I collect classic rifles and thus they figured that might translate to cars. I've always had good luck on forums and appreciate the knowledgeable advice I receive. Would anyone be able to tell me what value I'm looking at on such a vehicle? I know that this isn't a lot of information, but I'm trying to establish a starting point. The invoice for what they had done was 13 pages long and extremely expensive so I'll assume the entire car was overhauled. It was done by Steve's Hot Rod garage in southern Utah. I don't think they've put more than 50 miles on it since that time and it's been stored in their garage. Please let me know what I need to be aware of, any points that influence price, etc. Thanks again, and I apologize for the lack of information. I'm happy to answer any questions. Below is the link to the photo.

Here's the only one I have. I'm traveling down there this weekend to visit and am planning on taking more.

Nice truck. Post some more pictures when you can.  The invoices are important to prove what work was done but the dollar value of the truck will have no relationship to the cost of restoration. A sad fact most of us have learned the hard way.
