We bought a 1993 J-3o infinity in 2004 for 4,500 about how much was it worth in 2005?

My parents bought the car in 04 and then gave it to my sister in 05 as her first car. They said that they would put the same amount (as much as the car was worth when my sister received it) on my car. So I wanted a ball park of how much it was worth.
