I received more on my trade-in than the used car I purchased on 11/24/18. Since I purchased the car on a Saturday, I was told by their finance dept that a check would be sent to me the next business day (Monday the 26th). When I hadn t received the check after a week, I called and was told by the salesperson (Lindsey) they had to wait for funds to clear. Completely different than what I was told by the finance department. The salesperson had also said that she would look into the second key fob for the car I purchased and the additional set of floor mats that were shown in the sales photos. I never heard back from her on those topics. Very poor service.
