Wow, that is almost a re-body. Rear frame rails are rusted out ahead of the axle. He tried to take pics showing the floor is good, but I can see rust issues with the braces at the rockers, so I know there will be more.
Hagerty valuation puts a #2 car at $38,000 and there's no way this car would ever reach even that level and be under that price.
Neat car, but in it's condition, it would dang near need to be a give away to not go under water immediately. If it's for long term personal use, it would be a labor of love, like most of my junk...
