Salesman Devin Bratset made a deal with me on email for a 2020 Lexus RX450h. As we arrived at the stealership and after test driving and ready to pay, he said they changing the price because of the high demand reason, adding 3K more, wherein we just made a deal after five days ago. Dealership is trying to rip-off us after we like the vehicle. I made a deal online so that they can't push you to their pricing tactics and time consuming... Devin said he can beat the other price and offer me the 2020 Lexus RX450h for a price of 50K , that is why I drag my wife and scheduled to come to the Lexus of Concord dealership, but they just waste our time...
