I ran across an older (mid-eighties) passive Yamaha Motion B II at a local music store. It plays nice, sounds very good (if different) from my P basses and is super light. I did a little research but can't really say if this is worth the $400 they're asking for it (with original HSC); it's the one with the simple bridge, 32 scale. Were these considered high-end instruments in the day? Do they have any cool-factor or mojo I'm unaware of?
