When I returned to purchase a car after we had concluded the negotiations over the phone the sales manager greeted me with a racial slur. Twice they told me that something was required by state law that was not (I demanded that they show me the statute). They made me wait 90 minutes to pay the finance guy for the car. There was another person with the finance guy who kept asking the same personal questions over and over again after I had told him it was none of his business. They ordered me to sign a charity donation that comes out of sales tax money, which really was pushing their own political agenda. When I was paying the finance person, he wanted $ 4,000 more than the agreed upon price and I had to get him to correct the figures. At the end they insisted that I sign an arbitration agreement, that I did not sign. They did not provide a bill of sale. I would have walked out several times, except I wanted the car and the GM incentives were ending that day, so I couldn't go to another dealer (it was after 9 PM when I finally got out of the dealership, I had been there since 5 PM).
