The short answer
Based on available data, the Bentley Flying Spur comes out ahead of the BMW 7 Series 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
Owner sentiment is complex and heavily bifurcated by generation and ownership phase. The vehicle is universally praised for its presence, luxury materials, powerful performance (particularly W12 models), and supreme comfort over long distances. However, a very strong and recurrent theme across all discussions is the extreme cost and complexity of maintenance and repairs, which forms the core of negative sentiment.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Discussions indicate a split in engine preference.
Known issues
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.
