Wordpress Car Advertising Plugin

I require a plugin for wordpress that basically people can sign upto and sell there car. The plugin needs to enable the user to upload upto 5 images of their car and all the other usual information, mileage, price etc etc. It is free to create an account or sell your car, however there is a premium option that will cost a small fee. This will be a priority listing and will always show at the top. The plugin needs to be fully managable for the admin through the wordpress backend. The users account must be front end and editable.
