That Prelude has mis-matched wheels and a VERY long stem.
None of the those bikes are "clean, ready to ride" IMO. They all need work and, as someone mentioned a while back, if they need visible work you should be wondering about the bb, wheel bearings, headset, etc.
None of those bikes are worth their asking price in the condition they are in. Overhauled and ready to go - yeah. But not in the shape they're in now.
