I bought the PT Cruiser from a dealer like this.
I test drove it, seemed fine. It was priced at (I don't remember) $9K. The dude and I were chatting as I was looking it over. I found a massive pile of receipts in the glovebox, it was a one owner car and everything was there from the very first oil change to the last. I was ready to buy it for $8K. We talked, he said $8K out the door, no problem. I told him we were going across the street to buy lunch and we'd be back with a check.
We walked back in, dude said "oh man, I am so sorry, I don't actually normally work at this dealer, and I can't actually make that deal, you have to deal with this guy", and then "This guy" said "8,700 or no deal" or something, so I said "OK, cool. Nice talking to you" and left. They had three guys stationed at the door, and stopped me, trying to convince to to take out a loan for the $1000 and invest the $300 difference and use the interest to pay for the interest (real math wiz, this guy was). I told him (literally) that I'd leave there without my pants before I'd leave with a loan, and walked out. They had one more guy at my car. He knocked at the window, told me to come back. I said, if I come back, it's $8K out the door or nothing. He said fine.
They stopped me at the door and offered something stupid like $8,100. I said, literally "$8K out the door or I'm walking away, I really hate negotiating". Dude was laughing, and said "Really, because you're really good at it!". I did not smile.
I eventually got the car for $8K, but it sucked every minute of the process.
So, I guess what I'm saying is that unless you're buying it at Carmax (which is what I did with the van) you're going to be jerked around. Just accept it's going to be a pissing contest, and you're going to win or walk, and go back and buy the thing.
