Wow. I don’t know what else to say than that sucks! I got my car from a Mercedes Benz dealership in Connecticut which was being registered in NY (where I live). They agreed to the terms but during processing, they told me that Mercedes doesn’t accept MSDs because the car would be registered in NY. I argued that it didn’t matter as long as the dealership at point of sale was not in NY. The finance manager and I called Mercedes Benz Financial Service together in the office and I spoke to the representative there and he too told us that Mercedes didn’t accepts MSDs from NY owners. I told him that is not the case and that it didn’t matter as long as the point of sale dealership wasn’t in NY. He went to go check with his manager and he said that I was right.
It took a while and some fighting but I was told I was right all along. The finance manager commended me on knowing my stuff, and said that this was valid and if there were any issues, the call was recorded so that the fault would not be mine or the dealerships and that Mercedes Benz financial would absorb the cost of the mistake. At the end of the day, I was able to put down 10 MSDs and able to save a lot of money!
My advice - FIGHT FIGHT FIGHT! At the end of the day, they are just people who may be misinformed!
