The Arnage has the conservative look and feel of traditional big Bentley sedans, while Bentley's less-expensive Continental Flying Spur has a more modern style. The mammoth twin-turbo V8 engine in the Arnage is one of the smoothest, most powerful engines in the prestige luxury class, and its tremendous torque allows seemingly effortless acceleration and passing. Exclusivity and status is likely the primary reason for considering the Arnage, though; because Bentley only sells a few hundred Arnages annually in the U.S., you're not likely to see another.
