Yeah this stuff is all normal, the "mistakes" too. I had to make like 3 or 4 corrections after agreeing on an out-the-door deal. They just kept forgetting to update the paperwork etc. But you have to remember that this is part of how they make their money. If you want to finance elsewhere or pay cash, fine, but then the price of the car will often be more. That's why they will often not talk to you about the final price of the car until you tell them how you're paying. It's annoying. In my case, the dealership accepted my OTD offer on condition that I financed with them. I agreed, and then when they send me the terms I rejected them saying I wanted a much shorter term and a much larger downpayment. They didn't argue - but as I said I did have to re-enforce that change 3 or 4 times afterwards. I worked out the difference in what I would pay in total with various different rates, and the difference came out to a few hundred dollars. In the scheme of things it wasn't worth shopping around since I was getting more than that amount off the asking price of the car by taking their financing deal. tl;dr: always negotiate an out-the-door price. If the deal is contingent on you taking their financing deal, run the numbers and check. It might be worth it even with a higher rate. Also never trust the dealers calculations. They're padded.
