Whats it worth

It's worth the cost of scrap. Unless the owner is lazy or dumb. Then you might get it for less.

So 500-750ish

Hahaha.....

I was gonna say MAYBE a grand. It's rough, 273 cars are slow and boring too. Also, if you're gonna restore something and have a choice the early A's are hard to get parts for and are also equally harder to work on.
