I took the one out of my car and replaced it with a cassette so I could use my iPod in the car. It sold on the 'Bay for almost $250! I was stoked.
Just one note, the CD players in 93 were only available with the premium sound option. They have an amp under the passenger's seat and have a different hook-up than the non-premium sound cars. I had to make sure I got a cassette deck from a premium car.
