447033 Auto Classifieds Site

I'm looking to get a CMS classifieds site like this [login to view URL] It can be based on WordPress or even Joomla as a plugin. Features I need are Featured Ads, as well has have a option for free ads but the paid adds must get be up top. Also highlighted ads for free. people can signup as a member of the site and have a profile like a social network for free. Look at the site above and you will see what I need. Thanks
