You're taking a risk that you'll buy the car and then not be able to title it. Once the seller has your money, he's gone and good luck getting anything else from him.
If you don't know what documentation is needed by SC, GO TO the DMV office and ask. They will tell you.
Otherwise, follow my suggestion to have him bring the car and the papers to an SC DMV office before you give him any money.
