Stop in for a cup of coffee

What makes you assume it’s an unrestored original? Nothing in the ad says that. Just a GT slant with extra parts. For $15k? Really?
Sure looks like it from here. 68 Darts are hot right now. I don't necessarily think the price is right but it looks like an grandma's car. A cream puff. Looks like a pretty solid piece to just drive or modify. /6 cars are good for that. Most haven't been beat to death if they have survived this long.
