There are some real shaker fanatics out there that you pay a premium for real N96 cars, Challengers especially. This one is in a great colour combo and it's a four speed !
I don't think the asking price is that much off the mark, you have to start somewhere. I think a more reasonable price would be in a $10K range only because it's NOT going to be matching numbers when restored and the lack of a BCS is a huge negative.
The one I restored was very similar, no numbers, no sheet, needing metal work and missing parts...I believe it sold for $18K back in the day.
