I ve got a very bad deal, they offer you very tricky deal and ended up on a losing end. Very unprofessional customer service, got a deal before midnight realized it was a very bad deal went back to them the next morning, wanted to return the car, David told me I had to pay $3900 in order to return the car, I was seating for 2 hrs at the customer service area waiting for their Manager so I can explain my side no one even bother approach me or even give me a copy of our sales contract.
