Changed their agreed price for the car.
They did not have the car in stock but told me it would be available in couple days. We agreed on the price. I went there to put down my deposit and sign the agreement. Now they called me and told me the price needs to go up by $1500 due to an expired incentive from Honda. WTH? They are the dealer and should have known it, not me. To be honest, I don't even know what they said was true or they just decided to sell the car to someone else. I should have trusted other reviewers and stayed away from this dealer.
