I bought a new car 6 days ago, dealership was 'proud' to help me out and got me approved with Ford Credit at 0.9%. Yesterday, the business manager called to say HE had made a small 'mistake' and had put me in at the wrong tier...my rate is supposed to be 1.9%. He wants me to come in and sign a new contract. Can they do this? I think they need to swallow the $500 differential and make it up by selling an extra car this weekend. Is my signed original contract solid, or can they change this....what if I don't go sign a new contract?
