What's it Worth? 70 Dart Swinger 318

We found this 74 Dart Swinger on Craigslist for $1500 by the original owner here in Central Texas about two and a half years ago. I offered $1000 and they took it. I'm originally from Ohio and know that rust free cars are next to impossible to find up there. These are before and after shots of the car and no body work was required, just lots of elbow grease to accomplish these results. I know the further north we go, the more the cars value increases. We also have a 73, four-door donor car with a 318 that we got for $500 that ran and drove when we got it.
