Hi Kevin.....welcome to the Club

I would say that is just surface corrosion and it hasn't taken hold to much.
However, I would factor into the price the cost of having the underside completely Waxoyl treated which will neutralize the corrosion and also protect it for the future.
The Waxoyl should also be injected into the chassis rails and legs and also into the body panels as well

Let us know how it all goes
