Car Loan

I have had bankrupcy and repo in the past 5 years. my credit score now is 620 and they have me at a 15% interest rate. i had to have a car. my old one had over 200,000 miles, was 13 years old and was in need of major repair soon. my payments right now are doable, but eventually i would like to refinance for a lower rate. my credit history since all those issues has been fine. how long should i wait to refinace? i have heard e thing from 6mth to 2 yrs. also when i do, do i have a better chance of going through the same company? and.....should i try to pay a little more e mth now to pay off some of the interest or how does that work? i got the car for about $3000 less than bluebook price, so i got a nice deal. i think a lot of people that answered are thinking that i have had this car for a long time. i bought it with a 620 credit score and 15% interest rate.

You may have gotten the car for under blue book, but depreciation hits hard and fast. since most banks will only finance 80% of the value of a used car, you may never reach the point where you can refinance without cash up front. if you can afford to pay extra, do it. make sure they apply it to the balance instead of applying it as an advance on the next payment.
