The rust I would take into consideration. In that location, it is not too bad, but depending on where else it is. It is in Corning, NY, which is just south of me by an hour and a half.
i know there is a member down in the Elmira area who could look at it possibly.
If you want to see where the rust can occur and compare, take a look at the pictures of my Red SSE parts car.
Also, if you go to look at it, remove the back seat bottom and you'll know whether to keep the car or not based on any rust you might find there. The bottom can be removed with no tools
