Creating multiple content types using classifieds


I am trying to create a multiple classifieds website, for example a website that features cars, jobs, realestates, etc... I am using classifieds plugin and buddypress.

I tried to create post types for each classified section. For example, I created a post type called 'cars', and another one called 'realestates', etc...

Now, I am trying to create urls for each content type. All what I currently find is a link to classifieds from buddypress member menu, with all the links to create a new classified and so on.

Can you direct me to specific steps to establish what I am trying to do?
