I actually like car buying. The key is being willing to just walk away. Sounds like OP can do that without hesitation. When I bought my current truck, the dealer was, after much back and forth, finally within $500 of my buying and wouldn’t budge any more. I got up and left but told them I was driving right by my credit union on the way home and could easily pick up a bank check to them for the amount I had asked for. I got a call before I even got 1/2 way home.
