I recently bought a new Nissan Altima. I traded in my old Altima and I made the mistake of telling the dealership how much I owed on my loan. I was told they would give me the amount that I owed on the loan for the trade in. I waited a couple of weeks to purchase and in the interim I received phone calls (voicemails) from the dealership stating they would give mean extra $1000 for my car. When I went into the dealership I renegotiated the purchase price so of course the trade in value changed. They were only going to give me an extra $300. Ok fine. I reside in New York so when purchasing a new car and trading another car in simotaneously you only get taxed on the difference. While in the finance office for the dealership the amount being financed seemed too high so I inquired and some money was taken off. One of the things they said to me seems very unscrupulous. The finance manager stated they were paying off my loan but my trade in value included the tax reduction. It wasn't clear to me what that meant but since they adjusted the price and took off some fees I continued on with the sale. Now looking over my paperwork they gave me the agreed upon trade in value minus the trade in tax savings! Do I have any sort of recourse or is this a done deal because I signed the paperwork?
