Our Verdict
Caution is advised due to a recent MOT failure, though the vehicle has otherwise maintained a clean record. Consider negotiating the price to account for potential repair costs.
Prioritise checking the offside rear fog lamp and tell-tale system repairs following the 2026 MOT failure. Request full service history to verify maintenance consistency, as electrical issues are common in older Bentleys. Be prepared to negotiate the price due to the recent failure, and consider a pre-purchase inspection by a specialist. Avoid vehicles with repeated MOT failures, as they may indicate neglect or underlying problems.
The 5.9L petrol engine offers poor fuel economy, likely averaging 18-22 mpg. Road tax will be £520 annually (2023/24 rate for cars over £40k). Insurance group is likely 50+ (very high), with premiums exceeding £2,000/year. Major maintenance (e.g., engine or transmission work) could cost £5,000+. Estimated annual running cost: £2,500-£3,500.
Focus on the rear fog lamp and tell-tale system repairs, as these failed in 2026. Inspect electrical systems for corrosion or faults, common in older Bentleys. Check the offside front tyre (noted in 2024 MOT) for wear or damage. Verify the vehicle's service history for regular maintenance, particularly for high-mileage components like brakes and suspension. Look for signs of bodywork rust or panel gaps, which can indicate structural issues.
This 2017 Bentley Bentayga has a mostly clean MOT history with only one failure in 2026. The mileage of 69,958 miles is slightly below average for a 9-year-old vehicle, but the recent failure highlights potential electrical or maintenance issues. As a high-end luxury SUV, running costs and repair complexity will be significant.
No aggregate MOT data available for the Bentley Bentayga, but luxury vehicles like this often require careful maintenance to avoid costly repairs.
