You'll have to sell the car yourself vs selling it to a dealership to get anywhere close to what you should for it. But even then, if you're negative, you won't get what you need. So...my suggestion is to really research the value of the car, and then work your bottom off to pay down your loan to the proper amount. Then, when you sell it, you'll get enough to pay off the loan & get the title.
But...Dave says to get your $1,000 emergency savings BEFORE working towards paying off your debt. So for now, work to get the $1,000 and then work to pay down the car loan & sell it. After that, you'll be working towards saving for that next car (that you buy outright -- no loan) & other savings. It's so fun!!!
By the way, our church (in West Lafayette, IN) is offering Dave's class beginning in mid-January. If you are local, email me back so I can get you some information. Our leadership team just finished the study, and we made a $150,000 change in our debt vs savings as a whole -- in just 13 weeks. HOW AWESOME!!!! This stuff works!
