1970 c10 bagged value please??

[over40victimoffate]

I am considering buying this truck and I have been out of the market awhile. It is a 1970 c10 shortbed fleetside, bagged all four corners with 18" front wheels and 20" rear. I will include a few pics but he wants $15000. I was actually hoping to buy as an investment so I could drive a few months and resell. Is he in the ball park? Good running stock 350 and th350 drivetrain, painted a couple months ago and the wood bed is all new, new windshield. The gas tank has been relocated under the bed as well. Any input would be greatly appreciated. I hope i am in the write location for this thread. Thanks in advance.
