Here’s another drop by Jaguar in their quest to create a big hype for the upcoming 2010 Jaguar XJ sedan. This time it’s about the car’s aluminum body shell that is light and firm and blah blah blah! check out the video after the jump for more details. We have great respect for Jaguar, but we don’t like this sorta teasers. They are mind-numbingly boring! The actual car will debut July 9.
