Worst Dealer Ever. I went that dealer yesterday. They advertise on side of vehicle $15000 OFF, so I asked and confirmed their sales person and sales person confirmed that vehicle is $15000 off. So I give all my trade in vehicle information and spent over hour to purchase that vehicle, but later sales person said they can not offer that discount and just say goodbye and shake my hands. Never explain why thy can not give that discount, and they never honor this advertising on that specific vehicle!
And I asked salesperson, I want to speak with sales manager about this issue but refused.
