I compared it to the Dahon bike archives...it could be an older Mariner or possibly an older D6...can't really tell, but colors would go along with those models.
I just picked up a 2006 P8 from eBay...a pretty nice unit. The Craiglist-unit for $200 to $250, if it is in good nick, would be a fine intro to folding bike-dom.

2 - 2007 Custom Bike Fridays, 2 - 2009 Bike Friday Pocket 8's, Gravity 29'er SS, 2 - 8-spd Windsor City Bikes, 1973 Raleigh 20 & a 1964 Schwinn Tiger
It has the same frame latch and vertically adjustable handlebar as my 2005 Boardwalk Single-speed - not minuses, just age determiners. It looks like a 2003 or before - likely a 6-speed. There was a SPEED 6 in 2004 (shown below), but it had the newer frame latch and non-vertically adjustable handlebar.
I'd try for $190 sale price, assuming it is in good shape. Just my 2 cents.
You might also want to look around the internet to see what used Boardwalks are selling for in general.

I notice Dahon bikes evolve very fast. Each new years model seems 5-10% better than the previous year. So if this model is older than a few years, it is already 30% less of a bike than the latest model . Add wear and tear and I would not value it more than $150. You're better off getting a new one for $350.
