FWIW, I would put it on Ebay as is.
i sell a LOT on ebay....here is what I do:
run it first as an auction, with a reserve.
then run it a second time, as a "buy it now" with your price.
there's a lot of psychology that i don't feel like typing out...but it WORKS, i have ALWAY sold what I needed to, if the price was reasonable.
why get "trade" value when you can get "retail"
it costs ~$60 on each auction
also, FWIW, I did up a HUGE spreadsheet of how to figure out the "ROI" return on investmetn of going to a cheaper car for MPG (it NEVER does pay for it self)
i say keep it, drive it, don't worry about it.
i bought a Geo Metro for $800 while back, put $400 repairs into it, 36mpg & AC.
if you trade it in...you will prolly lose MORE on trade than a used Honda costs
