Orr Nissan

I purchased a Nissan Sentra in march of 2013 and the agreed upon price was the sticker price minus the $1000.00 Nissan rebate. I did not really look at all the paperwork for a few weeks but when I did I agreed upon price was the sticker price minus the $1000.00 Nissan rebate. I did not really look at all the paperwork for a few weeks but when I did I realized they had added a $987.00 "addendum" fee to the price. I called my salesperson and was told different things at different times (1) I don't know what it is (2) We add it to all cars (3) I don't think you paid it and (4) Ask the finance department. So I went in to ask the finance department and I was told that it paid for some oil changes and tire rotations. I later found out these were free and I never got an answer about what the $987.00 was for. I think it was dealer profit. The dealership refused to tell me what it was for so I currently have open investigations with the Louisiana Motor vehicle Commission and the Louisiana Attorney General. More
