Went and looked at it after work. Impressions:
Cold start lifter ticking for the first minute or so. Ran fine, ticking went away as it warmed up. Not bad (I've had bad lifters on an old car before), but noticeable.
When the dealer took inventory of the truck they replaced the front brakes (pads and rotors), the exhaust manifold bolts on the passenger side, both CV axles, serpentine belt, something else on the exhaust (I forget), wiper blades, and a few other maintenance items. Brakes are at 75% in the rear, 100% now in the front. Tires are 75%, lame looking highway tread but hey lol.
It has the Z71 suspension package, tow package, and has 3.73 gears with the G80 locker.
There is some rust on the frame, but all of it looks superficial. Not surprising given it is Ohio we're talking about. I'd probably wire wheel and coat the frame if I get it. Nothing crusty or flaky inside when I felt around in there.
No rust on the doors I saw offhand.
Some rust just behind the tail lights when opening the liftgate. Almost like the tail lights rub the paint off. Again, looks very superficial, and since it is behind the lights I could probably clean that up and spray some rust stopper paint on it and you'd never even notice unless you opened the tailgate.
It has a Tonneau cover on the bed. Bed looks to be in great shape.
Has a couple deeper scratches on the passenger side behind the rear door. Through the clearcoat but does not look to be through the paint. No rust.
Wheels have a little corrosion on them. 18" with 265/65/18 tires. To be honest I might switch to 17" wheels later, given the cost of 18" tires!
It drove really, really well. Holy crap I didn't think pickups could ride that nice. It felt huge too compared to the TB.
Oh, the salesman was really nice too. And as noted the pricing is like right in line with what it should be. No real wiggle room but when you already start out there then that takes the nuisance out of that part of buying anyway.
*edit* oh yeah they also are including a 30 day/1500 mile powertrain warranty. No deductible or anything like that, so if something went wrong during that time they'd cover it entirely. Yeah, only 30 days, but thought it was a nice gesture since most places won't give you squat for a warranty for a vehicle over 100k miles.
I'm really seriously considering it.
*EDIT2*
So I did research and it would seem the lifter noise is indeed caused by the AFM lifters. There is a TSB for that (10-06-01-007B) so I'm thinking of asking them to do that work as part of a purchase agreement.
