The short answer
Based on available data, the Mercedes-Benz GLS comes out ahead of the Maserati Levante 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
Mixed sentiment with a clear generational divide. Owner experiences are sharply polarized between those who report reliable, enjoyable ownership and those who face significant financial and mechanical hardship. A strong consensus indicates that model year is the single most critical factor, with 2019 and newer models (especially 2020+) described as having substantially improved reliability over the problematic 2017-2018 launch years.
Best version to buy
2019 and newer model years are overwhelmingly recommended over 2017-2018 models. For powertrain, the V8 models (GTS, Trofeo) are celebrated for their "Ferrari-derived" engines, sublime exhaust notes, and relentless power, described as the heart of the Maserati experience.
Known issues
Overall
Sentiment is sharply divided and heavily dependent on ownership phase and powertrain. The vehicle is universally praised for its core attributes: exceptional ride comfort, often described as "like a magic carpet," spacious and comfortable third-row seating, a luxurious and well-appointed interior, and strong, smooth V8 performance in 550/580/63 models. However, this high praise is almost universally tempered by severe criticism of ownership costs and reliability concerns beyond the initial warranty period.
Best version to buy
Insufficient owner data available to declare a single "best" version. Feedback is split by priorities: the GLS 450 is noted for being the entry point with a sacrifice in power.
