Consider also whether you'll sell the mirrors and keys with the doors. Those would add value. That said, around the Upstate of SC $800 for a clean set is what I'm kind of seeing online. I have a set that I'm about to sell. I'm keeping the mirrors and I don't have keys for the doors (it's my ignition key!). Mine do have some slight rust at the bottom of the door at the seam - not visible from the exterior. I'll probably start at $500.
