Seriously, was there any doubt that this would happen? Here's the skinny, verbatim, from Ford's press release:
The 2010 Mustang will be seen in the episode "Knight of the Zodiac" inside the Satellite Surveillance Chamber, also known as the SSC or "KITT Cave." The 2010 Mustang poses as KITT during an inspection and impresses everyone.
As crazy as it sounds, this particular bit of product placement may be more subtle than the pathetic shilling of Goodyear tires that NBC cooked up for last week's episode, during which KITT actually utters, "The tread is from a Goodyear Assurance ComforTread. It's one of the most popular brands of tires sold and distributed in North America." Somehow, I managed not to immediately kill myself upon hearing that and, as a result, I'll be liveblogging tomorrow night's Knight Rider pony parade. You know where and when to find me.
