It says zero rust, but I see some surface rust?

“Yes! You read it right! This is a factory CJ6 — NOT a 5, or a 7, a 6 from California. This is one of few. VERY RARE. And the oldest and only Jeep I’ve ever owned that has ZERO rust! Factory V6. PTO wench. 3 speed. Everything mechanically works great except the brakes will need gone through. Priced as is. On the back burner for now. As I do more, the price will go up. Comes with extra hood and original safari top. Not interested in trades unless totally in my favor. Prefer to sell. Serious inquiries only, please.”
