Were not terribly sure why watching Kate Upton hanging around a car thats getting washed by a bunch of guys qualifies as sexy, but apparently, it does. Mercedes-Benz proffers this new video ad as a prelude to its Super Bowl ad, which we think will also feature the supermodel who reigned in the Sports Illustrated swimsuit issue. Not a bad gig, if you ask us. She just sort of gets to hang out, and gets a paycheck for it. To Mercedes, of course, its the car thats the sexy beast of this ad. Its the new CLA, introduced last week at the North American International Auto Show in Detroit, and its aimed at the youthful, well-moneyed crowd that includes people such as Upton and her friends. But sexy? Were not seeing it. For sexy, try to the Carls Jr./Hardees hamburger ads that Upton already has tucked into her body suit. Now, those were sexy.
