Our Verdict
The 2017 Bentley Bentayga presents a strong value proposition with its clean recent MOT history and below-average mileage, though minor suspension wear warrants attention.
Prioritise checking the front suspension components for further wear, as the 2024 and 2023 MOTs noted worn suspension arm bushes. Verify service history to confirm regular maintenance, particularly for the diesel engine and complex Bentley systems. Negotiate based on the vehicle's low mileage and clean recent MOT, but factor in potential luxury car depreciation. Be cautious of hidden costs associated with Bentley-specific parts and servicing.
Diesel fuel economy for the 4.0L V8 engine is modest, with estimated combined consumption of 25-30 mpg. Road tax in 2026 would fall in the £155-£165 annual bracket for diesel vehicles over 15 years old. Insurance groups for luxury vehicles like the Bentayga typically range from 50-60, resulting in high premiums. Maintenance costs are elevated due to specialist servicing requirements, with typical annual expenses £2,000-£3,000 for parts and labour.
Focus on the front suspension system, particularly the arm bushes and associated components mentioned in 2024/2023 MOTs. Check for oil or fluid leaks under the vehicle, and inspect the diesel particulate filter for clogging. Test drive for unusual noises over rough surfaces to assess suspension integrity. Verify that all service records match the odometer readings and confirm no unreported accident history through the VIN check.
This 2017 Bentley Bentayga has a mostly clean MOT record, with only minor suspension bush wear noted in 2024 and 2023. At 44,614 miles, the mileage is significantly below average for a 9-year-old vehicle. While no aggregate reliability data exists for the Bentayga model, the vehicle's recent MOTs indicate good maintenance and no major defects.
No aggregate MOT data available for the Bentley Bentayga model, but this individual vehicle shows good maintenance practices with no critical failures.

AI Analysis
Historical fault & advisory patterns
Common Problems: BENTLEY BENTAYGA
Known issues reported by owners and MOT testers.
- Carbon Build-up (GDI Coking)(Moderate)
Direct injection leads to carbon deposits on intake valves, reducing performance and fuel economy.
- Infotainment and Electrical Glitches(Moderate)
The Bentayga's complex electronics, including the infotainment touchscreen, parking sensors, and adaptive cruise control, are prone to software bugs and random reboots. Moisture ingress into wiring can cause cascading electrical failures.
