I came here to make a 930 thread but I suppose I'll just tag onto this one.
I watch the 930 market fairly closely and the market over the last 3-4 months is going nuts.
Clean early cars seem to approaching six-figure sale prices with regularity. Later model cars are also being pulled up and I am seeing more asking prices in $60k-$70k range than ever before.
There is some good recent data in this thread in the 930 forum,
