Ok, I already said what I thought, but here is my rationale. I don't know the miles or condition or trim level of your car, but would put a value of around 5K on a 2004 LS sedan with average milage. That said you owe 3.3K, so you net 1.7K minus any deductables. Tax and tags alone will probably be around 1K, so you net a down payment of 700 bucks minus any deductables. I wouldn't want to buy a used car cause you already have a used car that you know more about than the one you will buy. Therefore this is why I said I would probably live with the dings. I think it will cost you more in the long run.
