Just bought a car with capitol one. Need information

So I just bought a car today around 12k. From a ford/ haundi dealership. I got a haundi. Anyways, they said I got pre approved for capitol one. They had me sign documents and contracts. I traded my old car as well. Now I don't have good credit but since I have a credit card with capital one they said capiotlcone will approve me for the loan. So I signed contracts and drove off with the car. Now, is the financing approved? I can't call capitol one because they care closed but I want to sleep tonight I don't want the delership calling back asking for the car back or pay higher APR. What's your input on all of this?

The dealer is not going to let you drive the car off the lot unless you have the loan approved. Did you get a copy of everything that you signed. Capitol One will not raise your rate. That's why there's a contract. It's to protect both sides. You can't say that you got a lower rate and C1 can't say you have to pay a higher rate. The contract says how much your rate is.

Have you read the contract or not? That's the 1st thing to do
