AKA 'portholes', as seen on Buick's (and, as you'll see here) quite a few other cars. In their purest form, a means of letting air move through an otherwise solid panel. Over time, they became stylized representations of 'real' ventiports. This photo collection is open to all who wish to join in. However, please don't include contemporary automobiles, especially those with stick-on portholes from the discount auto parts store. Old customs, where the builder used real metal parts, and in many case, cut holes in the fenders to mount them, are A-OK.
Here is a selection to get us started. As you will see, some of these have previously been puzzle subject cars right here at AutoPuzzles. Enjoy!
