On this episode of Head 2 Head, Motor Trend's Jonny Lieberman gets behind the wheel of two of the finest long wheelbase luxury sedans - the 2013 BMW 750Li and the Jaguar XJL Supercharged - to see which one of them does justice to their $100,000 plus price tags. First, Jonny heads to the track to see what kinds of numbers these large, premium sedans put down, then he sees how they both handle on the rough roads outside of Santa Barbara, before finally getting chauffered in the back seat of the cars to examine their distinct approaches to high-end luxury. So which one will stand out as the best in its class? Stay tuned to find out.
