Honda Cars of McKinney

I bought the car from Honda Cars of Mckinney, when i bought the car they offered me 2.9 APR. Since i am getting low APR even thow increased my Car price i bought the car. After 3 weeks of car delivery they called me and saying that my loan is not approved and asked me look finance by my self. When i went to finance by myself with bank i got 6% APR which will increase my total payments. But when i asked to reduce the car price with the dealer, since my interest rate is gone up, they said they will not reduce. Please be aware of this sales manager and also aware of their finance guy. I never recommend this dealer to buy a car.
