Help with VIN...

I believe the "S" means it is a 'Cuda instead of a Barracuda, which would have an "H" in the second spot of the VIN. For example, BS23H3 would be a '73 'Cuda 340 and BH23H3 would be a '73 Barracuda 340.

Pricing is impossible to tell without pictures or an extremely detailed description.
