So has anyone been working with Mercedes Benz of Oklahoma City? I went by yesterday to build my CLA and possibly pre-order it. First off, they were very rude. The salesman barely knew the name of the car and had no clue about it. I knew more about the car than anyone in there. When it was all said and done, I asked if they would be negotiating prices because I know of other dealers that have offered up to 3% off the MSRP. His response: "3%? No way, that will not be happening here." And that was it. I said thanks and walked out. Has anyone else had good luck with the dealers in Oklahoma?
