Hi I'm Ladd. Thought I would check this out to find news on Smarts. Mine should be on 7/21/2008 ! Would like to find a way to hook a backpack type carrier on the bottom half of the rear. We will be occasionally travelling with our little Cockapoo [Pixel] and would like to have a carrying mechanism on the back for those few occasions. I saw the rucksack, but it goes on the top half, is a little too big and covers up the rear window. How about a trailer hitch for the smart fortwo?? Thanks. y'all. from South Carolina
