The short answer
Based on available data, the Maserati GranTurismo comes out ahead of the Porsche 911 on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Sentiment is mixed and highly dependent on owner expectations and maintenance approach. The vehicle is described as an "emotional decision, not a logical decision," prized for its intoxicating Ferrari-derived V8 engine sound, striking design, and the visceral, comfortable grand touring experience, often compared to a "leather couch strapped to a Ferrari V-8." However, this generation is subject to widespread and severe criticism for ruinous unreliability, questionable build quality, and massive depreciation. The interior is frequently cited as dated, senseless, and prone to specific failures like sticky buttons and bubbling dash leather.
Best version to buy
Insufficient owner data available to specify a best trim or model year. Owner discussions focus on the model generation as a whole rather than comparing specific variants.
Known issues
Overall
Sentiment is deeply polarized and varies significantly by generation and model.
