70 dart 4-speed 340

Hey guys, first post!
I'm looking to buy this car in my area and wanted to get a few opinions on it. Owner claims it's super rare but needs a bit of work. A 340 dart restored, same color but auto sold in my area for $35900. I believe the price may be high but you guys judge. Any info would be great.
