What is a rusty '66 Formula S worth?

Personally something ain't right...If its been in the family since new then why is that emblem placed so high and the Barracuda Script emblem is missing??? Are both fenders like that? Maybe it was in a major front end collision in which both fenders were replaced from a 'non' Form. S Barracuda. And who knows what other hidden damage it may have. Personally if the seller can't explain it then I wouldn't buy. (no offense to either party) Without more pics and more info. it's worth $300.00 if non Form S. & $800.00 for Form S. to me.
