Seems a bit high to me. On the outside it looks really promising, but you need to hear it run and take it for a spin. Short of that, you don’t know how much of a money pit you have.
My truck looked good, but had not been running for several years and had a newly rebuilt engine 5 years prior, with paperwork to prove it. It had a whole folder full of receipts. Aside from that it needed cab corners, a cab floor and new wood in the bed. That’s what you could see.
Turns out the rebuild was done by a shoddy shop and needed to be completely redone to the tune of $2,000, with me doing the assembling. It also needed the tranny rebuild, rear axle rebuild, a complete brake job, including new lines master and wheel cylinders, complete spring rebuild, complete front end rebuild, gas tank cleaning, complete rewiring and I haven’t even got to any bodywork. I’ve put $6,000 (not including the purchase price) into this project and I did the work (aside from the engine machining).
The point I am trying to make is unless you can drive that truck at close to highway speeds, testing the steering, brakes, gears and listening for abnormal noises, you won’t know what you really have.
IMHO, if the truck runs and drives OK, $9,600 is the high point of the negotiations and I would try to get that down at least $2,000.
