Update:
I ended up walking away from the deal after seeing the truck in person. There were several reasons, but the main ones being it was in very rough cosmetic shape (red carpet stains, ink stains on seats, a lot of scratches inside and out, tape lines on front fender and bumper where it had been painted), had an oil leak (assuming drivers side cam tower), and the seats were tan despite being advertised as charcoal. Pretty disappointing, but I went with my gut. For perspective, it was in much worse shape than my 2001 LC with 200k, so I know the most recent owner did not take care of it. Also did not find any service records or receipts in the glove box to address my concern about a gap in records from the carfax. The PO racked up 30k miles in a 12 month period with zero service records.
Finally, it had a cheap $40 battery in it, which always bothers me. Who puts a cheap battery in their car? I mean, a good battery is only $130! We're talking about a car that was $70,000 new, and you want to put a cheap battery in it?!?! Sorry, it's just a pet peeve of mine...I feel like if you would cut corners on a battery, you would most certainly cut corners on major items.
The salesman asked if there was a number they could get to given all the issues. I told them it would have to be at least another 2-3k off. They weren't interested in taking much more off the 31k, and claimed they had already turned down a 35k bid from a wholesaler, but were giving me first dibs since they had already been working with me (obviously this is BS). I've been around car salesman long enough to know the last thing they're interested in is my wellbeing. So know I know why the price was so good.
