What's the price?
Does it run?
Check carefully for rust around the back wheels. Look under the rear fenders for inner fender rust. There are NO reproductions from the door to the back so metal work for rust can be tricky.
If there is no rust along the bottom of the truck from the door to the rear bumper I would be surprised. The slider windows allow water to run down into the body. Over time dirt fills the space where the water would drain and rust developes from the standing water.
Just a few things to think about. I will tell you a pre 1960 burb is an attention getter no matter where you go. They are soooooo rare.
