The possible ending of Carnival of Cars is a sad thing, and Mark has stated that he's uncertain if it will reapear with his move.
But nature abhors a vacuum and Gary Grant of the Garage Blog has started a Carnival of Wheels feature, where he will pick up the torch from Mark and feature submissions from around the automotive blogshpere.
