I'd say WAY less than 50%. Probably more like 20% or so. I've parted out a bunch myself that are no longer with us so to speak. The comment about the rarer cars surviving at a higher rate is probably accurate, T/A's AAR's, 6 Packs and Hemi cars probably approach the 50% margin but remember a lot of these cars also ended up wrapped around poles especially 4 speed cars.
