I just came back from checking it but no road test because of a heavy rain. I am supposed to drive it Sunday if he still has it. BIG crack in the dash on the driver's side. The tow ball in the pic was for an aluminum boat on a trailer. Very light. Trans cooler lines leaking. Several small scratches all around but not into the primer so could be buffed out. Steering wheel has sections where the outer layer is rubbed off but no gouges. The one large knob in the picture on the lower left of center dash has all the insignia's rubbed off. Power steering pump leaking behind pulley. 4 speed trans. Inside is really dusty and dirty. Think his wife has a small dog but did not see claw scratches on leather seats. Has the driver's seat rubbed thru at the rear side area where the wife just falls out of it when she gets out. She is about 4'6" tall. The driver's side window has a regulator going out. Lots of squeaking, grinding, squawking noises going up and down. Oil was clean and so was the coolant and trans fluid. The brake fluid was dirty. I will look at the paperwork he has if I go for a road test on Sunday.
All in all I was a bit disappointed with what I just saw as opposed to what he represented. He said he would take $500 off for the paint buffing but I didn't get into the fact that I would still not pay the $11,000 after that credit is taken off. Maybe I am just cheap but I still need t road test and right now I would not give more than $8000 for it.
This is really common and normal stuff for a 12 year old vehicle. You will be very lucky to find one that doesn't have the dash cracked. I replaced transmission cooler lines on both of mine, both have some buttons peeling, both have wear on the steering wheel, both required an extensive detail (I even pulled the seats and console out of mine) and buffing after buying, both got new seat cushions in the driver's seat, both got ALL fluids changed, both got new steering gears (my truck was leaking and her truck was making a rubbing noise), both have had all four front control arms and front springs replaced, both have had rear air shocks replaced (with GM units). The squeaking window regulator can be fixed with GM Super Lube, it was a very common issue for the first few years of these trucks.
The main thing I'd look out for with a black one is the paint starting to peel on the hood and roof. If it's been garage kept most of or it's whole life, it should be good. People don't wax their cars like they used to which helps. You're looking at a 12 year old car, be prepared to spend at least a few grand on any one you look at.
