All original CSX and 30k miles of track might translate to less than market value, unless it has a history. However, an unmolested car that is in decent order would be big dollar as they can never be brought back to original state once restored. They can only be unmolested once....
I assume we are talking 289 street car?
CSX2345, unrestored FIA (might be 63 car?) Millions......
Slabside street car ~ $550k to $600K as the recent sale of CSX2485 had proved.
Unrestored and good condition is a rare find and a highly prized car!
