Our Verdict
This is a strongly recommended purchase for buyers seeking a well-maintained luxury SUV, with a clean five-year MOT record and low mileage for its age. The absence of any recorded defects across all recent tests suggests careful ownership of this 2017 Bentley Bentayga diesel.
Given the unbroken clean MOT history from 2022 to 2026, your main focus should be on verifying the service history with a Bentley main dealer or specialist, as luxury vehicles of this type require documented scheduled maintenance to retain value and reliability. Negotiate on the basis of the low 45,196-mile reading and the flawless MOT record, but be aware that the diesel variant may carry a ULEZ or clean-air-zone penalty depending on the buyer's location despite its Euro 6 status being typical for 2017 models.
As a 3,956cc diesel Bentley, this Bentayga will sit in one of the highest VED tax bands, likely over £600 annually for the first licence, with subsequent renewal around £195 as a post-April 2017 diesel over 40k g/km CO2 threshold. Insurance will be expensive given the marque and engine size, typically in Group 50, with premiums often exceeding £1,500 per year for comprehensive cover. Estimated annual running costs including fuel, tax, insurance and routine maintenance are likely in the region of £3,500 to £5,000, excluding any unexpected repairs.
The MOT history shows no failures or defects of any type across the last five tests, so there are no specific failure patterns from the record to investigate; however, you should still commission an independent inspection to confirm the diesel powertrain, air suspension, and electronics are in good order. Pay particular attention to the 22-way seats, infotainment system, and panoramic roof if fitted, as these are common high-value items on the Bentayga that are not captured by a basic MOT. Confirm the mileage of 45,196 is supported by service stamps and previous invoices to rule out any discrepancy with the recorded progression from 32,031 in 2022 to 45,196 in 2026.
The 2017 Bentley Bentayga registered LL17XJT has covered just 45,196 miles as of its most recent MOT in January 2026, which is low for a nine-year-old vehicle. Every MOT from 2022 through 2026 has passed with no defects recorded, indicating consistent mechanical and cosmetic condition. Finished in blue with a 3,956cc diesel engine, this example appears to have been lightly used and properly cared for since its first registration in March 2017.
No aggregate MOT reliability data is available for the Bentley Bentayga, so this assessment relies solely on the individual vehicle's clean test history.

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.
