Let’s try a little speculative math here:
At $800 a month, you’ll pay off the debt in 12 1/2 months. A thousand bucks would knock a month off. If you did that right now, how much would that save? At least the current month’s interest, plus consistently decreasing portions of the interest you would have had to pay on that grand for the life of the loan.
Since my math skills are terrible, I won’t even go near this problem, but you could probably get a rough estimate. (or some helpful doper could try, hint, hint).
On the other side, there’s the amount that grand would earn in your savings account for a year.
Compare the two figures.
That’s one element to figure. Here’s another: if your car dies, what kind of hassle do you have to go through to get it fixed or to buy another one? By that I mean both physical trouble (getting the car to a shop, getting rides to work), and financial (do you have any credit at all? Could you put the repairs on a credit card?)
And if you have to buy a car suddenly, what kind of deal would you get with no ready cash available?
So there’s two values to consider: a straight dollar-for-dollar calculation, and the emotional toll it would take to CYA should you have no money in your savings account and the car’s engine blows on the freeway while you’re coming home from work.
Myself, I would opt for determining what your plan would be for your next car, and figuring how much it would cost to get there. That would determine how much you need to save. I’m big on paying car loans off as soon as possible, and I have two paid-off cars (a '90 Festiva, my combat commuter, and a '94 Caravan, the family car) to show for it.
Final answer: there’s no right or wrong answer here. You ARE doing right to pay down the debt, fer sure, but after that, your financial goals and your comfort level with being in debt will determine what your next move should be.
Nothing like asking for answers and getting 200 opinions, eh?
