New Toy GMC Shortbed 4x4

[house6860]

Well I'm new to the the old GMC truck game but think I found a good starter. Purchased from a 74 year old man for what I hope was a reasonable price. None the less I'm now committed to the truck and the joy of ownership. Bucket seats, tach in dash factory air, automatic with tilt wheel. Sierra model, 350 Ram Jet engine that runs well. Now I usually must have a factory all original equipment truck but it's so hard these days to find a all original truck that's in repairable condition in a short bed 4x4 without breaking the bank. Not sure what it's worth but hoping more than I paid. Any educated guesses on its actual value would be greatly appreciated.
