My long-distance critique based on not-so-great-quality zoomed in images:
Dash pad is shot.
Windshield sash was either put in wrong, painted, or is broken.
Drivers side marker is broken.
Bumper trim piece is screwed up on passenger side front bumper.
Serpentine belt routing sticker is not all there.
Something is up with the core support paint.
Tailgate panel appears to be ruined from improper cleaning?
Top (from all I've seen) appears to be too glossy, and the seams somewhat filled with paint, meaning it's been re-painted.
Rear bumper has obviously been hit or hit something, as it's wavy on the drivers side all the way to about the license plate frame. I'd be looking on the inside of the rear quarters for dents/bondo.
Drivers side taillight is not aligned with body right.
Yes, I picked the truck apart based on 4 pretty grainy photos, and for some issues that are extremely minor. No, the truck is not "pristine", and if the seller told you that, is a liar and there is no way in hell I'd give him the money if I couldn't SEE $7500 of value in the truck (like a professionally installed LS-whatever 6L and one ton running gear, that was setup exactly as if I had it built on a hit tv reality show). If I can see that many problems with a "pristine" truck from four photos, imagine what a trained eye will see in person?
As a matter of fact, on principle alone I wouldn't do business with him at all if he indeed said it's pristine. Maybe I'm getting cantankerous, but I'm tired of dealing with people who are outright liars, fraudsters, or just plain jerks. I'm tired of people selling stuff under false pretenses, assuming buyers are A) too stupid to know better, or B) hoping that once there you will just buy it because you took the time out of your life to go check it out and might have the money in your pocket. I no longer have the inclination to find later what the seller knew to be true when they misrepresented it to me, unless of course I know it's a great buy, and I'm willing to accept the risks. It's your money, perhaps your definition of pristine is different than mine, and if so, that's perfectly acceptable.
$7500 might be acceptable where rust claims these vehicles back east in short periods of time, and clean examples are indeed rare. But everywhere else? Slapping a coat of paint on a 23 year old truck that has obvious issues doesn't make it suddenly worth $4000 more than it's competitors.
But without dragging out the dictionary, I'm sure that doesn't fit the definition of pristine, at all.
