Ebay today launched U.S. version of Kijiji, a direct competitor to Craigslist. Currently most categories are empty and have no ads... be the first one and post your ad and take advantage of free PR. The process of posting a car ad to Kijiji is very similar to Craigslist.... HTML is restricted and you must upload the images.
Why should I post to my cars to Kijiji?
Well one thing it is getting press coverage and there are no ads in most categories so for few days your ads will be the only ones in the categories. They have the SEO part pretty well down.... the site is pleasing to look at... one can contact the poster right from the ad... my eyes don't hurt when looking at the ads... search functions are way superior... site navigation is rock solid.
