I looked at eBay completed auction prices for MBs.
No MB-Zips. MB-1 complete bikes have sold for $350, 480, 1870. MB-S for $305, 1500. MB-3 for $255, 290, 300, 400. I'm surprised the MB-3s fetch that. The >$1000 bikes are immaculate and their buyers don't intend to ride them, I'm sure.
Speaking of vintage MTBs, another one I really like is the Ritchey P23. On eBay, when they come up, they are usually $1200-1500.
