73 duster value

Sitting around watching it ran, flood watch alert going on so I checked out the list for dusters and parts. There's an ad on there, that's been up before for a 73 duster. First time was, make any offer of cash. Well he really wanted $1800.00, it's a /6 missing carb, rear wing window, trunk has been pryed open with a crowbar heavily damaging the trunk lid and taillight panel. Non running for years in a field. It's back up at $1200.00, trades, part trades or best offer. Thinking about building a 2nd big block duster. Body work isn't an issue, we have tackled worse. What do you think it's worth as a reasonable offer to him? I've not figured out how to post the ad on the thread, I'll ask my kids to help me later, but if you want to check it out, it's listed on the Dorena, Oregon craigslist. "73 plymouth duster project" $1200.00 any suggestions welcome. Maybe it's more of a parts car then I think it is. Let me know what you think.
