Do you think I can get a car loan?

My credit is bad. It's 550. I'm Self-employed I make $71,000.00 a year. I went to a jeep dealer and found an 2008 jeep for $20,000.00 and the loan is for $17,500.00. I sat with the guy he said he can get me done. That was on Saturday. I filled out the paper work and the credit application through ally financial. He even gave me an delivery date to take home. Now I'm waiting to see approval. Do you think i can get the loan.
