I bought an Altima last night, obviously the banks for approval was not open, the car was 17,000. I had already had a pre-approval from my credit union for only 15,000. I did not use the pre-approval because the dealership said they can give me a better interest rate, than my credit union. which they did. So I drove off the lot with the car. The bank called me to verify employment, etc.. but didnt know I already have the car, if financing don't go through do you think the dealership will take my pre-approval check that I still have for 15,000 so i can keep the car, and risk losing the difference,or will they send me on my way and take the car back. PLEASE HELP ME OUT!
