Yahoo! Autos has uses a nice hybrid design pattern for promoting the different categories of top cars selected by users. Situated in the right hand column, the arrows at the upper right allow the user to slide through the different lists. The details for the top car are shown in an exposed panel of the accordion, and the titles of the remaining 4 are displayed as well with large number to indicate order. Moving the cursor over one of the other titles slides that panel open and collapses the others out of view.
