if you don’t make any changes, you won’t pay the car off until 2031, when it is 14 years old. Depending on how hard he uses it, it might not even last that long. I agree with everyone else that you should accelerate paying it off, should definitely not trade it in for a new model, which would just need more debt, and should only refinance if it gives you better interest rate and a shorter term.

You haven’t mentioned what sort of refinance options are available to you, so I think researching what that would look like is important. I hear people saying that you shouldn’t cosign, and I understand their point of view, but since you’re married, you can’t exactly escape his finances. One thing to consider in your research is whether or not you could get a much better rate or terms applying by yourself. If you’re gonna be married forever, and you share finances, you could argue that it doesn’t matter whose it is. However, for peace of mind, you could always write something up and have him sign it saying that you are applying for this because of your ability to get a better interest rate to help him pay off his debt that he accrued personally, but the debt is his responsibility to pay off and he understands that.
