The short answer
The Audi A7 offers fuel economy, while the Lexus LS excels at power instead. Choose the Audi A7 if you prioritize fuel economy in daily driving, or the Lexus LS if power matters more for your needs. Both are covered by real owner reports on CarWizz.
Overall
Overwhelmingly positive sentiment regarding the driving experience, design, and long-term reliability of the 3.0-liter supercharged V6 gasoline engine (3.0T) and 3.0-liter TDI diesel powertrains. The A7 is consistently praised for its gorgeous, timeless design, exceptional comfort, refined handling with Quattro all-wheel drive, and practical hatchback body style. Owner feedback indicates high satisfaction with the vehicle's performance as a daily driver and long-distance cruiser, with specific acclaim for its quiet cabin, comfortable seats, and high-quality interior build.
Best version to buy
The 2016-2018 model years with the 3.0T supercharged V6 gasoline engine (CREC version, 333 hp) are most frequently recommended. This iteration is noted for having design revisions that address earlier potential issues like carbon buildup (via dual port and direct injection) and updated chain tensioners.
Known issues
Overall
The sentiment is overwhelmingly positive, characterized by deep owner loyalty and satisfaction with the vehicle's core mission of providing unparalleled long-term comfort, refinement, and reliability. The LS is consistently described as a benchmark for a "decade-plus" ownership experience with minimal drama, offering a sense of solidity, quietness, and effortless power that makes other vehicles feel "a bit cheap by comparison." While there is strong consensus on its supreme comfort and build quality, nuanced criticisms exist regarding specific model years and components. The LS460 (2007-2017) is praised for its bulletproof V8 but noted for expensive wear items like control arms and air suspension.
Best version to buy
For the LS460 generation, later model years (e.g., 2017) are implied to be more refined and reliable than early first-year models (e.g., 2007), which are described as "Toyota's bastard child for reliability." For the current LS500 generation, the LS500h AWD with the "Teammate" advanced driver-assist system is mentioned as a highly capable but rare and expensive configuration. There is no single trim consensus, but the underlying recommendation is to seek well-maintained examples with full service histories, regardless of specific year or trim.
