1966 Dodge Dart GT - Trying to Determine How Rare

We don't know a few things: What you have in it ($$$), what you plan to do with it, condition of interior, suspension, etc....

I think if you like it and want to KEEP it, if you are in at $12-15K or less ALL IN, I say you're good. But if you plan to flip it, I'd stay under $7-8000. (FYI: I'm in the SF Bay Area, so this is my perspective. You're in Kansas I see ... I don't know what the economy is like out there. My two cents....)
