No and no.
The bitch selling the vanagon - I offered to fix some of the starting problems for her for free, and look over the rest of the stuff it had going on for free when she bought it. She conned the dealer into doing it. When she whined about not having good enough tires to transport her child, I offered some HD rated good-tread tires on vanagon wheels at less than cost to her. She never responded.
She posted it for sale for $300 and I told her I would take it. Cash. She responded saying she'd been offered $750 and I needed to top that offer. I said no thanks.
Later, she emailed and asked if I would pay $400. I said sure - she told me to call her later.
Fuck that. I don't allow myself to be shiestered. It might still be a good deal, but I'll pass.
