Set 4891, Highway Haulers, was released in 2006. It contained 209 elements and cost only US$10. As with other sets in the Creator and Designer lines, there were instructions for several models you could make using these pieces--in this case, six different vehicles--and also pictures of ten other possible creations as inspiration to the builder.
Brickshelf user zFERRY has posted pictures of all of the models with instructions and also several of the alternate models.
