Be careful. I went to buy a Nissan, agreed on the price with certified warranty. I went there the day after to purchase it and the warranty was not included, when I had confirmed the price with them, with certified warranty included, 2-3 times before going to buy it. Ceritifed warranty was my requirement from the beggining of the negotiation in order to buy the car.
They increased the price and they told me that if I wanted it certified I had to take it by myself somewhere else to change the tires, and bring it back so they can certify it, I thought it was a joke but was for real.
Do not waste your time as I did. I ahould send them an invoice for the time they made me waste. Very unfair and unprofessional negotiation practice, looks like a scam to me.
