Glass is in perfect condition, exterior has some very minor wear. The AF motor seems to have gone out, but you can still manually focus without any issues.
Honestly, if I didn't already have a second lens I'd probably just send it off to Nikon for repair. Should be a basic fix, but I don't really have the time to put into getting this fixed.
