<prompt> Human: Ive been approved for a Lightstream auto loan for 20k at 2 APR, Credit score 800. I work two jobs, and tomorrow I have a few hours spare in the second half, and want to make the most of it. Found three cars online all Camry Avalon CPOs that meet my specs, and Im hoping to test-drive them tomorrow, and then make a purchase. Ideally, Id like to get everything done tomorrow itself, but Im afraid that in my rush, I might be making some stupid decisions here. First, Lightstream said that if I completed the online agreement etc, they could transfer all 20k to my bank account, and then I could pay the dealer by a check. Is this legit? Out of the door, if the car costs 17,000 instead of 20,000, the Lightstream rep said that I could return the extra funds through a pre-payment no pre-payment fees, or just make my monthly payments on the full amount of 20k. Again, sounds too good to be true. Am I missing something here? Does any of this have taxIRSreporting implications, since the amount is pretty high? Can the dealer scam me in any way, because Im making a 100 cash check, actually payment? Sorry, after years of driving a beat-down car, Im finally upgrading myself. This is my first big-ticket purchase, and I wanted to be sure that I was doing it right...PF, give me some advice please.  <response>: Ive financed through lightstream a few times, I love how easy they are to work with.Yes, you can ask for more and just pay them back or use the extra for whatever. Its an unsecured loan, they dont really care.Theres no tax implications. Its a loan, not income.Cashiers check is the way to go and gives you a great bargaining tool. I bought my last car by having the check made out for the amount I was willing to pay for the car. Makes it a lot easier to walk away and for them to make a deal when you show them the check.
