<prompt> Human: My Mom and Dad are going through a divorce and my Dad had her only car, that was under his name repoed as revenge. He just stopped making payments.My Mom needs transportation and went and found a new 2018 Nissan Rouge.She has terrible credit but co-signed for my car 2 years ago, a 2013 VW Jetta. Its underwater and Im the one making the payments on it. It wasnt that I had bad credit, I just hadnt established any at the time and her credit is bad.Now my credit score is in the high 700s and my Mom needs me to co-sign in order for her to get this new Nissan Rouge.I plan on refinancing my VW Jetta with my bank to get out from being underwater on it. Will co-signing on my Moms car right now prevent me from doing that?EDIT: Seems the consensus is the same with everyone posting. I wont be going through with the co-sign. Thank you all for the advice!  <response>: I know you didnt ask but, honestly, if the bank wont take a chance on her, neither should you.She needs transportation, not a brand new, off the lot car. She needs to find a car that she can afford on her own.I know that wasnt your question but if you decide to co-sign anyway, it could impact your ability to refinance. Without knowing specifics, its hard to say for sure.
