What owners say
7 Series
Overall
Sentiment is mixed and heavily dependent on generation and ownership phase. Long-term owner reports for older generations (e.g., E65, F01, G11/G12) highlight significant concerns regarding high maintenance costs, complex electronics, and expensive repairs as the vehicles age, particularly when professional labor is required. These models are described as "over-engineered" with components prone to failure, leading to substantial out-of-pocket expenses.
Best version to buy
Insufficient owner data available to designate a specific "best" trim or model year. One owner of a 2015 diesel model reported satisfaction with its fuel economy, but no consensus exists on optimal configurations.
Known issues
- ⚠High maintenance and repair costs: very expensive parts and labor, especially for electronic components and engine-related repairs. Frequency: very frequent.
- ⚠Complex electronic system failures: issues with control modules, sensors, and infotainment systems that are difficult and costly to diagnose and repair. Frequency: recurrent.
- ⚠Engine reliability concerns: specific mention of complicated, over-engineered engines (e.g., N63) that are expensive to fix; turbochargers noted as costly bespoke items on performance variants. Frequency: recurrent.
XJ
Overall
Sentiment is deeply divided and heavily dependent on the specific generation and powertrain. For the classic X300/X308 (mid-1990s to early 2000s) and the Ford-era X350/X358 (2003-2009), long-term owner feedback is mixed, with strong praise for their distinctive styling, luxurious interiors, and driving experience, but severe criticism for reliability, aging poorly after high mileage, and costly repairs. The aluminum-bodied X350/X358 generation, in particular, is noted for its rust-free construction and more reliable naturally-aspirated 4.2L V8, with some owners reporting affordable maintenance using common Ford/Lincoln parts.
Best version to buy
For the X350/X358 generation (2003-2009), the 2006-2009 model years with the naturally-aspirated 4.2L V8 are recommended to avoid early issues present in 2004-2005 models. The Super V8 (SV8) trim is highlighted as a particularly good example.
Known issues
- ⚠Cooling system failures: plastic pipes, thermostat housings, water pumps, and crossover pipes become brittle and leak, requiring comprehensive replacement. Frequency: very frequent (across multiple generations).
- ⚠Electrical and infotainment problems: from blue-screen failures requiring a full reboot in older models to pervasive electronic component failures (instrument clusters, battery drains) in newer ones. Frequency: very frequent.
- ⚠Aging interior materials: door handle cables breaking, adhesive failing on trim, leather and wood deteriorating, especially in high-mileage examples. Frequency: recurrent.
The verdict
