The short answer
Based on available data, the Maserati GranTurismo comes out ahead of the Mercedes-Benz CL 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
Owner sentiment is highly conditional, centered on the significant and well-documented maintenance costs associated with the complex Active Body Control (ABC) hydraulic suspension system. The vehicle is universally praised for its timeless design, luxurious feel, and potent V8/V12 engines, offering an exceptional driving experience when fully functional. However, the consensus is that ownership is a high-risk, high-reward proposition, suitable only for those with substantial maintenance budgets and access to specialized independent mechanics.
Best version to buy
Insufficient owner data available to designate a single "best" version. Discussions indicate a trade-off: earlier models (pre-2003) are noted to have first-generation ABC components with known issues, while later facelift models (2003+) may have addressed some of these problems.
