Is there any such thing as a good source of what Zs are selling for? Hemmings seems skimpy. There aren't many old Zs here in OH because our winter road salt rusted most of them away, so we rarely see ads for them locally. I've got an early '70 that spent most of its life in CA and AZ and now winters in my garage. It's solid and rust-free. I would assume that prices vary geographically. Now I'll listen. Thanks.
