<prompt> Human: Today I went to go buy a car I have been looking at for a while. It was listed at 21,000 and they offered me 5,500 for my trade so that would have made the cost 15,500... right?Well they go about doing the numbers with the good cop bad cop scheme with the manager and come back to me with 425 a month for 72 months. I totaled that up and it was 30,600 and Im like... what the hell. I asked them what the interest rate was 3 times and they looked at me like I was the dumb one. Granted I am a 24 year old woman, I know what an interest rate is. Can someone check my math here, did they just try to offer me a 100 interest rate almost??I stood up and walked out of there without giving them another word. They have been texting and calling me but I am so appalled.Edit: Credit score is 580, trade in is paid off. Me and my husband bring in 4K a month. Also they tried to get me to not put him on there and only use my income because he has no credit yet. I was looking at a brand new honda. They said a lifetime powertrain warranty was included. Thank you for everyone who gave me good solid advice. As for the people saying I should keep my car, I cant. Its a 2013 Ford focus and the transmission is shot. Ford says there isnt anything wrong with it. There is currently a class action against them. I dont know why my credit is low. I paid off my last car with no late payments at all. I have a couple credit cards that I pay on and have never been late and some hospital bills that I refuse to pay. So I dont know.And to all of the rude people going through my comment history and harassing me, go find something else to do. Sorry for going missing, I had to be up at 5AM to work!Some of these comments are making me feel like straight shit though. In my part of the country we dont make a lot of money. Im a college educated certified CPhT not a fucking fast food worker.  <response>: Dont buy a new car. Your credit score clearly reflects that you dont understand credit and make poor choices with it.
