The Neiman Marcus Christmas Book is a holiday tradition for many, but not all the cars that have been offered in the book over the years have proved as collectible as the buyers might have hoped. Fifty eager Jaguar buyers have placed their bets against that eventuality for this year's offering, as the 2010 Jaguar XJL Supercharged Neiman Marcus Edition sold out in just four hours.

Sales started noon Eastern time last Friday, and before close of business, all 50 examples of the car were spoken for, with just four hours and four minutes required to move every last one of them.

Priced at $105,000, that's a cool $5.25 million, or about $1.3 million per hour. Not too shabby even by Neiman Marcus and Jaguar standards. As fast as that is, however, it's not the quickest seller Neiman Marcus has seen. In 2006, the Neiman Marcus BMW M6 sold 50 units in just one minute, 32 seconds.

The Neiman Marcus XJL features a unique appearance package, with Celestial Black paint and navy/ivory interior leather with Zebrano matte wood accents. Twenty-inch split-spoke alloy wheels, illuminated tread plats and a custom nameplate that denotes each car's 1-50 serial number also mark the car out as something beyond the typical production 2010 Jaguar XJL.
