You can look it up at Kelly Blue Book or Edmunds TruMarket Value. Both sites are good...plus they can give you closer values based on where you live, the color of the car, etc. There's other sites; I did all this research before I bought my 95 SE back in January.

according to nada, your car is worth 9475 retail,7750 wholesale or trade in value,6975 loan value. you should be able to sell it outright for around 7500 to 8000 yourself. the car dealer will give you about 5000 trade towards a new car. and then turn around and sell it for 10995 if he has second chance finance deal, or about 8995 for cash or a credit union deal. hope this helps.
