The Rolls-Royce Ghost occupies the 'pinnacle' segment of ultra-luxury sedans, competing alongside the Bentley Flying Spur, Mercedes-Maybach S680, and the Cadillac Celestiq. While its starting price exceeds most direct rivals, the Ghost justifies this premium through its proprietary 'architecture of luxury' chassis and the effortless prestige of its V12 powerplant. Ultimately, while competitors offer impressive luxury, few can match the sheer grandeur and gravitas inherent to a Rolls-Royce.
