What would you consider "fast" for a supercharged luxury sedan? 160 miles per hour? Five seconds to sixty? How about four hours? That's how long it took Neiman Marcus to sell out its limited run of special edition Jaguar XJ's featured in this year's Christmas catalog.

By itself, there's not that much that sets the Neiman Marcus edition apart from a stock 2010 XJL Supercharged. It's got a special paint job and a numbered plaque. But more importantly, like the luxury department store did last year with the new BMW 7 Series, this year's luxo barge of choice hit the Neiman Marcus catalog before it becomes available to the public. Which could go a long way towards explaining how, within four hours and four minutes of the car's availability, all fifty of the $105,000 specials were gone.
