Would it be better to refinance my car or buy a new one?

About a year ago, I bought a car from one of those "no credit, no problem" dealerships and got an interest rate of about 20% (no comments on my poor financial decision lol). Anyway, in about a month, I will be getting between 6 and 10 thousand dollars and I was wondering if it would be a better idea to refinance for a lower interest rate or trade in my car and use the money as a down payment for another car. Keep in mind, the only credit I have is from the payments on my current car, which is a 2004 Honda Accord Coupe EX.

Refinance. If the car suits you well then no need to loose money on trading in.

oh wait, you're getting 6-10k and you got 2004 Honda Accord Coupe EX? Pay it off!

Just pay off your car
