Whats the value of...

[1969 GMC]

I know I will get yelled at for this, but I think I have a good find pretty close to my house. Only thing is, its a Ford.
This is a bit of a mystery but...when I was originally looking for a truck, I just wanted any old domestic 4x4. Chevy, GMC, Ford, IH, whatever, just needed to be stick shift and 4x4. Well, my dad found this truck...it is a mid 70's Ford F-250 4x4. It's not a 78-79, it's the style before that. The interesting thing about it is it only has about 6,000 miles on the odometer. It has been sitting in front of this house for a really long time. We stopped to ask the owners of the house about it, but I think the house is abandoned. However, the grass was freshly cut. The truck is sank to the rims in the ground. It is sitting under a big tree, and the drivers side of the cab is pretty moss-covered. However, you can see inside. The interior is immaculate, and not sunburned (cuz its under this huge tree). The seats, seatbelts, and carpet look untouched, nicer than my mom's 2001 Honda Civic seats. There are plastic bags on all the pedals. The shift pattern is easily readable on the knob (4 speed). There are pieces of paper that say "Ford" on the floor over the floormats. I think the dash says "Custom," not sure however. All thats wrong w/ the interior is the rearview fell on to the floor. We decided not to open the hood since we cannot find anyone at the house, but we did crawl underneath it. It has the 300 ci I6, I don't think any other sixes were available for Fords back then. Dana 44 front, Dana 60 rear...probably NP205 t-case. Underside of truck is clean enough to eat off of. Literally. Metal still looks metallic in front and rear fenderwells. Only rust is along the bottom of the tailgate is rotted thru. Tailgate works fine. Bed is full of water and dead leaves, and small plants grow in it. But, it holds water, so its not rusted thru. Its a bronze or copper color. Firestone mud tires...dry rotted and flat, but probably the originals. Ohio plates, last tagged in '91, which is kind of odd. I really believe this is a true 6,000 or so mile truck, from the looks of it. I have been trying off and on to get ahold of the owner of the house, I did a search in the library directory by address, and found the owner and a phone #. But the phone just rings, no one answers. Left a note on the house's front door with my name and number, no replies. There was also a FedEx pkg on the stoop, so someone else thinks he still lives there. I did an internet search for the owners name, and i found a local church website, of which he was a contributor to in Dec. of 2002 (last time I called, before I got the GMC). My question is, what do you think this truck is worth? If possible, I'd like to buy it and have it towed to my house on a flatbed, and fix it up. True, its a Ford, but when do you find something like this? Almost never in that good of shape, especially here in Ohio. And sorry for the long post. If wanted, I can probably go take some pics of it. Thanks
