Specs side by side
What owners say
6 Series
Overall
Sentiment is mixed and heavily dependent on the specific generation and powertrain. The 6 Series is widely admired for its styling, described as "sexy" and "beautiful," and is considered a desirable, emotional purchase. However, long-term owner reports consistently highlight significant concerns regarding reliability and high maintenance costs, particularly for models equipped with V8 engines (N63).
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Anecdotal praise exists for the post-LCI (Technical Update) F12/F13 650i with the N63TU engine, noted for improved reliability over the pre-LCI N63.
Known issues
- ⚠High maintenance and repair costs: very frequent. V8 engine reliability concerns (N63): oil leaks, cooling system failures, requiring tows. Frequency: recurrent.
LS
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.
Known issues
- ⚠**LS460 Generation:** * Control arm and suspension bushing wear: Requires replacement far too often, as frequently as every 60k miles, with costs exceeding $2,000. Frequency: very frequent.
- ⚠**LS500 Generation:** * Early powertrain reliability: The 2018 LS500's new twin-turbo V6 had "early teething issues" compared to the previous V8. A manufacturer recall for engine debris affecting some 2022-2023 models is mentioned.
- ⚠**General (All Generations):** * Excessive weight and handling: The car is described as incredibly heavy, with tires and wheel wells too small for its mass, leading to compromised cornering and braking feel. Frequency: recurrent.
