<prompt> Human: To start off, I already realize that I made a rookie mistake of not shopping around for financing and going to the dealership pre-approved. TIFU, I know. However, the dealership gave me the impression that the financing was already in order, as they had several days with my information before I came in to sign all of the paperwork, and had the financing terms.So the numbers:I have a good credit score of 728, and a steady gross salary of 66,000, plus about 2,600 per month in non-taxable per diem. Prior to purchasing the car, I had roughly 40,000 saved up between my personal checking and savings accounts. The car I purchased was 28,995, and after warranty, registration, taxes, etc., the total came out to 33,230. I put down 5,000, and the remainder, 28,230, would be paid over 84 months at 397.68 4.84 APR, bringing the full cost car taxes fees interest to 38,405. I understand my budget and was comfortable with these installments, even considering the length of time and the cost of interest.Heres the issue: about a week later I received a notice in the mail from the credit union the dealership had set up that they would be unable to extend credit to me at this time. The reasons were Limited credit experience and Other: Additional co-borrower required for consideration of loan approval. It did not provide any further instructions.I have not heard yet from the dealership, but I suspect I will soon. Worst case scenario, I have the cash on hand to pay the full price minus the interest, but I would rather not. What options do I have? Would it be a good idea to pay it in full?Thanks in advance :Edit: Thanks for all the responses! I dont have time to reply to everyone, but I will definitely take these into consideration. To clarify, yes its a lot for a used car, but its a 2014 Wrangler with only 40k miles. These things average in the high 30s and even 40s. I looked at a lot that were more expensive for an older model with more miles. I need a good reliable car that will last a long time up in Michigan roads and weather.I will be calling my bank and maybe a couple credit unions to see if I can finance it, and almost certainly put down a larger payment. 84 months is... indeed a long term. There is no penalty for paying early, but if I am refinancing anyway, I might try to shorten that. And again, I could pay the entire thing, and still be better off financially than I was a year ago, but I just am not sure if thats smart or not. Thoughts? Thanks again and wish me luck!I finally have a good TIFU story, so at least I have that going for me.  <response>: A 7-year car loan for roughly 12 your annual salary??? Ouch!From your OP above it sounds like the dealership set you up with the financing the dealership gave me the impression that the financing was already in order. If it fell through then IMO its time to play hardball with the dealer.You have a chance, just a chance, to hand the car back into the dealer youve only put 2 weeks worth of miles on it and it was already used to start with and get your 5K back. Do it.Its too much car and too long a term. Get out of the deal if you can. Say dealer, its your problem since you said you got me the loan. And no, I dont have anyone that will co-sign.Then maybe up the ante and offer to buy a much cheaper used car from them for cash or something you can pay off in 2 years. They can either 1 just take the car back and give you your 5K, or 2 take car back give you your 5K youll buy a cheaper used car at a good-for-OP price from them.
