Just posted in the "Best of Craigslist" thread but thought I'd mention it here too: just saw a 2009 Dahon Glide P8 being offered for $550!! Does that sound like a reasonable price to you?
I emailed the seller to ask why she's selling it and she said she'd been using it for commuting by train, but her job's changed and she has to drive to work now, so doesn't really need the bike anymore.
Since I don't have the $$ at hand right now, I asked her to let me know if she hasn't sold it in a couple of weeks ... theoretically I could buy it if I have time to pull the cash together ...
Meantime, there's also a Dahon S1 Boardwalk going for $180 - again, does that sound like a reasonable price? (assuming it's in good condition, of course!)
