Found a K-code coupe with a bench seat for $7,500. It needs restoration and the owner states it's 90% rust free, whatever that means? I've got a call into him to get some more details, but how rare are the K-codes with benches, and let's say this is a non-running project, and maybe needs the floors replaced or something to that affect, would it be worth $7500 if the hipo is still there?
