Since you get to try it out in person, take some time to see how it feels, plays, and sounds. Pretty obvious to say, but I sometimes get focused on unimportant (to me) things when I feel pressured. I personally could care less about a bit of a neck gap if it plays and sounds great, but for some people that's a no go. If you can, take a look at the first 5 frets or so to check out their condition. Judging by the rest of the bass in the pics, I would think there would not be much wear. I had a '75 that looked exactly like that one except it had a white pickguard, in great condition as well. The pickup foam had melted into sludge, but when I took them out to clean up the mess and replace the foam, the pickups were dated to my birthday on the nose. Pretty cool! The neck was noticably beefed from front to back which I think is normal for that era. Also, check the truss rod screw and make sure it isn't bottomed out or won't turn.
