I generally sell my cars on enthusiast forums and have had very good luck doing that...Questionable if that car has any enthusiast following at all, but if there is a forum, put the ad up there.
Otherwise, Autotrader and Craigslist if you want to stick it in there with the Mass of similar vehicles being advertised. Just be aware of Craigslist...While it may be good to secure a local buyer, the Scammers work that site pretty hard. Just be careful.
