Our Verdict
This 2018 Bentley Bentayga presents a strong case for purchase due to its clean MOT history, but buyers should exercise caution due to the lack of model-specific reliability data and the inherent complexities of luxury diesel vehicles.
Prioritize verifying full service history to confirm maintenance standards, as Bentley vehicles require meticulous care. Negotiate based on the vehicle's below-average mileage, but be prepared for higher-than-expected repair costs due to its luxury status. Check for any outstanding manufacturer recalls specific to 2018 Bentaygas and inspect documentation for proof of regular servicing. Be wary of potential hidden costs associated with diesel particulate filter (DPF) maintenance, a common issue in older diesel vehicles.
As a diesel-powered luxury SUV, fuel economy is likely to be modest, with typical combined figures around 25-30 mpg. Tax band depends on CO2 emissions (likely £1,000+ annual road tax for 2026). Insurance groups for Bentleys are typically in the highest brackets (e.g., Group 50+). Maintenance costs will exceed average family cars, with major services potentially exceeding £1,000. Estimated annual running costs: £2,500-£3,500, excluding depreciation.
While the MOT history shows no defects, inspect the diesel engine for signs of DPF issues (e.g., warning lights, reduced performance) and check for oil leaks common in older Bentleys. Examine the cabin for wear on premium materials and verify the condition of the 4.0L V8 engine through a mechanic's report. Pay close attention to the all-wheel-drive system and suspension components, which are critical to the Bentayga's performance. Confirm that the vehicle has not been involved in any accidents using the VIN check.
The Bentayga has maintained a clean MOT record across five consecutive annual tests, with mileage of 69,485 miles (8 years old) below the typical average for its age. While no aggregate reliability data exists for the model, the vehicle's consistent MOT passes suggest responsible ownership. However, its luxury status and diesel engine may introduce higher-than-average running costs.
No aggregate MOT data is available for the Bentley Bentayga model, making it difficult to assess long-term reliability trends.

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.
- Fuel Leak Recall(Serious)
Early V8 models were subject to a recall for a potential fuel leak from the fuel line quick connector.
- 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.
