Over 100k isn't surprising for the 2915s. 50k is a new high for a 2998-1 but a long time coming; the other 2998s in your post were about where they usually are. The real craziness is in the 105.012s, which both sold for nearly double what they were worth just last week....

I fully expected my Speedmaster 105.003 to be the last straight-lug model that I could afford, but unfortunately all 321s are likely to go up in price beyond my reach now.
