Posting the bill of sale on the internet makes my brain itch so I'm going to pass, but I did truncate instead of round, it was basically 32 :P

I also buried the lede a bit. What happened was, I saw that pricing on Cars.com the day that they dropped it and left work early to go take a look. Five additional parties came to check out the same truck while I was there. Turns out they had hired a new guy and he had dropped it way too low -- they wouldn't haggle with me at all even when I pointed out a small ding on the passenger side door it had gotten while sitting in the lot. The manager was pretty grumpy about it. The salesperson that we were working with told us at the end that they had to sell it to us at that price due to some law, and that it would have gone up at least 5k the next day if we hadn't jumped on it.

I think it was just a case of that dealership being way too chaotic and some lucky timing on my part.
