<prompt> Human: Long story short, back in 2016 I bought a 2016 mustang. I was single and the car worked great. Flash forward I now have a girl friend who lives with me and a black lab puppy who will get big and a mustang isnt the right car anymore.She has an old civic for when we need it, but we want to get a 4wd car, we live in an area where we get snow, and a big 4 door awd car is just roomier. Im a pretty tall guy, 6 foot 5.My mustang was a 7 year 0 interest loan. My question is should I try to go back to Ford and work a deal, go to carmax and try to work a deal? If I go to carmax, how does the future payments work? Do I sell them my mustang and buy their car with tthe mustang money and continue to pay of the 0 mustang loan?Money is obviously an issue here, but Im understanding i will most likely lose a little money if I go through with this, Im ok with that.  <response>: How much is your car worth today and how much do you owe? Since its a mustang youre probably upside down
