I recently purchased a used car. During test drive a sensor light was on in the vehicle. The salesman said it was due to low tire pressure and they would fix it. During the paperwork process the cost of the vehicle went up by $1,400.00. I asked why, The finance manager stated that it was due to bank fee's. The finance manager stated that I needed to tell the bank I paid $6,000.00 cash on the vehicle when In fact, I traded in a vehicle and paid no cash. After expressing concerns about the sensor light on to the manager, I was told they would correct it. Once I arrived the next day, the initial salesman told me that they were not paying for it. I demanded to speak to the manager. The salesman jumps up threatening to attack me, asked me to step outside and had to be restrained by staff.
