Careful. It seems like the seller knows nothing about this bass (or bass in general), and that throws a red flag to me. It's probably stolen. The body, tuners, electronics, bridge and everything but the neck are not original. Not even the neck plate! My suspicion is that someone put this bass together (poorly) for themselves, and then it was stolen and put up on craigslist.
Actually it smells of "Pawn Shop" to me. The carpet in the picture is industrial grade carpet squares, not what you would normally see in a house. There isn't anything about this bass that would be worth paying for.
Tuners - garbage
Body - broken
Neck - modified and in doubtful playing condition
Controls - knobs missing, caked with crud, pots probably packed with dirt
Bridge - caked in crud, allen screws corroded
Neck plate - not original
Fat finger - drilled into
Drop key - possibly not working correctly
Upper strap pin - not original
Strings - judging from the amount of crud on this bass probably trashed
I wouldn't buy it to own, fix/flip or even part out. In fact I wouldn't even take it for free - it would probably take around $300 to get it up to gigging quality (assuming the neck is ok) and then you'd be lucky to ever get your money out of it if you sold it.
The OP made a wise move - "move along, these are not the droids you're looking for"
