I very badly want my dad's name off my car title, which I can't ask him for until I can prove his name's off my car loan. My last payment, if I don't lump-sum it when the refund shows, is in May. That payment is twice my next biggest loan payment, so the sooner I can use that part of the budget for other things, the better. On the other hand, the credit cards I'll pay if I don't pay off the car are the same ones I'd be paying with the ex-car-payment money if I do pay off the car, and the interest rates on those cards are about twice the rate on the car loan.
(It would be bad of me to buy the learn-to-piano software I want and the learn-to-sing software I want and the cute fannish denim jacket I want with some of the refund money, yes? It would be okay of me to buy one of these things, or a couple books adding up to the same dollar figure, with some of the refund money, yes?)
ETA: I asked my mother, she asked my father, and he says if he's not on the title, I can't be on the family insurance. Solo auto insurance is probably more expensive. I'll have the money for it, given the reduction in monthly total loan payments, but.
ETA2: Looks like a solo policy through my family's insurance company, assuming the same level of coverage as now and no loan on the car, will cost two-thirds my share of the family policy. The difference in a month's premium comes very nearly as high as what I'd save on interest by paying the credit cards; two months, I'm making money. Sold.
