Our Verdict
The 2018 Bentley Bentayga presents a strong value proposition for luxury buyers, with a clean MOT history and low mileage for its age. However, its high running costs and potential for expensive repairs mean it’s best suited to those prioritising prestige over economy.
Prioritise verifying full service history, particularly for the 4.0L V8 engine and complex electronics. Check for any unpaid outstanding service reminders via Bentley’s official records. Negotiate based on the vehicle’s low mileage and pristine MOT record, but factor in the high cost of specialist repairs. Be wary of 'cosmetic' fixes that may mask deeper issues. Insist on a pre-purchase inspection by a certified Bentley technician.
The 3.996cc petrol engine delivers strong performance but lacks efficiency, with estimated fuel costs of £1.50-£2.00 per litre. As a luxury vehicle, it falls into a high tax band (£520 annual road tax for 2025/26). Insurance groups for Bentleys typically start at 50+, with premiums exceeding £2,000 annually. Scheduled maintenance (e.g., oil changes, brake services) will cost £300-£500 per service. Combined with fuel and tax, annual running costs are likely £1,500-£2,000.
Despite its clean MOT history, inspect for signs of wear in the 4.0L V8 engine and its complex drivetrain. Check the air suspension system for leaks or unusual noises, a known weak point in older Bentaygas. Examine the interior for wear on the leather upholstery and wood trim, which can crack over time. Verify that all electronic systems (e.g., infotainment, climate control) function correctly, as software issues can arise in older models.
This 2018 Bentley Bentayga has maintained a clean MOT record across six consecutive annual tests, with no defects reported. At 29,174 miles (as of July 2025), its mileage is below average for a seven-year-old vehicle. While no aggregate reliability data exists for the Bentayga model, the vehicle’s consistent MOT performance suggests good maintenance. The petrol engine and premium build quality align with Bentley’s reputation, though running costs will be significant.
No aggregate MOT data is available for the Bentley Bentayga model, but its consistent MOT performance here suggests responsible ownership. Bentleys generally require more frequent maintenance than mainstream vehicles.

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.
