The short answer
The Audi A8 offers fuel economy, while the Maserati Quattroporte excels at power instead. Choose the Audi A8 if you prioritize fuel economy in daily driving, or the Maserati Quattroporte if power matters more for your needs. Both are covered by real owner reports on CarWizz.
Overall
Sentiment is generally positive among long-term owners, particularly for the D5 generation (2018+), which is praised for its exceptional ride comfort, quiet cabin, advanced technology, and strong value proposition on the used market. The D5 is frequently described as a "hovercraft" for its sublime, non-floating air suspension and is noted for being significantly lighter than its rivals due to its aluminum construction, contributing to better handling and fuel economy. Owner satisfaction is often tied to purchasing the vehicle as a lightly used or CPO example at a steep discount from MSRP, where its blend of luxury, technology, and driving dynamics presents a compelling alternative to the Mercedes S-Class and BMW 7 Series.
Best version to buy
For the D5 generation (2018+), a well-optioned example is highly recommended. Key desired options include the Executive Package (22-way seats with ventilation/massage, head-up display), Driver Assistance Package (adaptive cruise with traffic jam assist), dual-pane acoustic glass, the premium lighting package (HD Matrix LED, OLED taillights), and the Bowers & Wilkins audio system.

Overall
Sentiment is sharply divided and heavily dependent on the specific generation and powertrain. The consensus indicates that the vehicle is a deeply emotional purchase driven by passion for its design, sound, and driving character, not rational ownership. The Ferrari-developed 4.7L V8 models (circa 2004-2013) are frequently described as "fantastic," "beautiful," "iconic," and "intoxicating" to drive, with a sublime engine note and a "classy, baller feel." However, these older V8 models are almost universally associated with very high maintenance costs, expensive parts, and a high likelihood of significant reliability issues, particularly with early automated manual ("F1") transmissions and electrical systems.
Best version to buy
The 2009-2013 Quattroporte S or GTS with the 4.7L Ferrari-derived V8 and the ZF automatic transmission is most frequently cited as the desirable version. This configuration is praised for its glorious engine, improved transmission reliability over the earlier "F1" automated manual, and the classic Pininfarina design.
