Last month, we told you about Nissan and Sports Illustrated partnering up to put on the first ever Sports Illustrated Model Search. Eight models from around the world are competing in the search, and the winner will be featured in the 2012 Sports Illustrated Swimsuit Issue. You can vote for your favorite model by visiting the Sports Illustrated Model Search website. Voting ends tomorrow, so make sure you visit the site today and cast your vote for your favorite model.

Nissan and SI rolled out a series of new videos to promote the model search this week. The videos feature Kowalczyk, the office-saving, donut-hunting driver from the Nissan Juke commercials and the extra-fine ladies of the SI Model Search. The series, titled “Rookie Slot,” follows Kowalczyk as he rides his Nissan Juke to Vegas to meet the models and pick up a very important bag. Take a look at the four videos in the series:
