What owners say

Mulsanne

Overall

Sentiment is mixed to negative, with a strong consensus that the vehicle failed to meet expectations for its class and price. The model is frequently described as underwhelming, particularly in direct comparisons to key rivals like the Rolls-Royce Ghost and Mercedes-Benz S-Class, with one specific media review cited as being "brutal" and highlighting the car as "truly awful" by comparison. Owner discussions reference significant depreciation, with one report of a new vehicle remaining unsold for two years and eventually selling for approximately 54% off its original MSRP (approx. $200,000 USD vs. $437,000 USD equivalent).

Best version to buy

Mulsanne Speed: Isolated feedback specifically highlights the "Mulsanne Speed" variant for its superior performance, suggesting it addresses some of the dynamic criticisms of the standard model. No detailed trim comparisons are available within the data.

Known issues

  • Severe depreciation: New vehicle reported unsold for two years, selling for a massive loss. Frequency: isolated but highly specific.
  • Prohibitively expensive and complex repairs: Parts are described as prohibitively expensive with lead times of weeks or months; specialized hydraulic brake and suspension system noted as particularly complex and reliant on obsolete compone…

Phantom

Overall

\nThe sentiment derived from owner and enthusiast discussions is overwhelmingly positive, positioning the Phantom as the definitive benchmark for ultimate luxury, refinement, and presence. The vehicle is consistently described as offering a "surreal experience" of quietude and isolation, with its ride quality characterized as effortless and serene, to the point where the sensation of motion can feel disconnected from visual cues. It is held as the standard against which all other luxury vehicles are measured, frequently cited as having "no finer car interior." The primary critique, mentioned in isolation, pertains to the use of some shared switchgear and software from its corporate parent, which some feel is incongruent with the vehicle's bespoke price and image.\n\nSentiment Confidence Level\nMedium (Positive sentiment is strong but based on a limited number of substantive experiential references).\n\nFrequently Mentioned Competitors\nBentley Mulsanne, Mercedes-Benz S-Class Maybach, Rolls-Royce Ghost, Rolls-Royce Cullinan.

Best version to buy

\nInsufficient owner data available to designate a specific model year or trim as "best." The Phantom Extended is noted for its available "Privacy Suite" with features like electrochromatic glass, catering to buyers seeking maximum separation from the driver.\n\nRecommended Configurations\nInsufficient owner data available for specific configuration recommendations. One mention suggests the Phantom Extended for those desiring modern privacy features.

Known issues

  • \nUse of shared parent-company switchgear/software: some controls, dashboard layout, and software are visibly shared with more mainstream models, which is noted as a minor disappointment given the price and bespoke expectations.
