I think it is still salvageable but is worth $0 in it's current condition. Believe it or not, this can happen very quickly and mold grows on all surfaces. Our 1976 Corvette wasn't driven for a few weeks this spring. The seals around the t-tops leaked when it rained and the entire inside of the car was covered in mold. Metal parts, plastic parts, carpet and all. Needless to say, we nearly had a heart attack. It was a big job cleaning it and very time consuming. If you clean this yourself, use a mask, long rubber gloves and cover your clothing somehow. Don't use bleach, it will ruin it. Once it is completely cleaned, every nook and cranny, inside and out, it may be worth about $60.
