do you know what its worth ???
if so why not a classified ad, in the uk its cheeper and lasts for a month.
people can see what you want and you can alter the ad anytime its listed so reducing the price or additional info is easy to do.

you stil get nob shiners but thats ebay.
by doing what i mentioned you almost avoid the people with no clue who value your car at nowhere near its true value if its doing 800 dollars for example and hope to nick it off you because they think you have no clue either
