Is the Bentley Bentayga reliable?

The Bentley Bentayga scores 93/100 on Forecourt's MOT-based reliability measure, ahead of 100% of the cars we track. That is computed from 18,723 real DVSA MOT test results.

How much does a used Bentley Bentayga cost?

A 2023 Bentley Bentayga with around 20,178 miles is worth roughly £111,600 today (typical range £97,450–£125,800). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.

How quickly does the Bentley Bentayga depreciate?

A new Bentley Bentayga typically loses about 30% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.

What insurance group is the Bentley Bentayga?

The Bentley Bentayga sits in insurance group 46 of 50 — the more expensive end of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.

What goes wrong on a used Bentley Bentayga?

The most common age-related issues we track for the Bentley Bentayga are: tyres & wheels (typically around over 100k miles, £80-£500 to put right); suspension (typically around over 100k miles, £150-£450 to put right); seat belts & restraints (typically around over 100k miles, £80-£250 to put right). A full service history and a recent MOT with no advisories are the best protection.

What does the Bentley Bentayga cost to run?

Expect around 22 mpg combined on the Bentayga V8, £200 a year in road tax, about £290 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.

Is the Bentley Bentayga ULEZ compliant?

Most petrol Bentley Bentaygas from 2006 and diesels from September 2015 meet the Euro standards for London ULEZ and other UK clean-air zones, so they are generally exempt from the daily charge. Pure-electric versions are always exempt.

How many Bentley Bentaygas are on UK roads?

About 4,153 Bentley Bentaygas are currently taxed and on the road in the UK, from DfT vehicle-licensing data.

Bentley Bentayga

The Bentley Bentayga is the definitive ultra-luxury SUV - the car that proved a Bentley could be a 4x4, pairing immense power (W12 or V8) with a hand-crafted cabin of leather and wood that nothing this side of a Rolls matches. Vast, hushed and surprisingly capable, it's a limousine that happens to be an SUV. As a used buy it offers staggering luxury for the money relative to new, with the inevitable complexity and running costs.

How these figures are sourced — the valuation is anchored to a researched used-market price for this model (AutoTrader median, 2023 at 30k miles). Reliability, mileage and variant data are real DVSA MOT records. Dimensions, tyre sizes and costs, servicing figures and the insurance group are segment-level estimates rather than sourced per car, and are being replaced model by model.

The short version

76/100

Forecourt score

Value 92 · Reliability 95 · Insurance 4 · catalogue percentiles

The Bentley Bentayga holds its value well and is dearer to run than most. Its MOT-based reliability is excellent — an MOT score of 93/100, ahead of 100% of the cars we track. On three-year value retention it ranks better than 92% of models.

The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20) — the from-new ownership picture. Higher is better; running cost is not yet folded in.

MOT pass rate by age

A 3-year-old Bentayga passes its MOT 95.6% of the time; by 10 years that has slipped to 95%. The y-axis is zoomed to this model’s range so the trend is readable.

Survival by registration year

78% of 2018 cars still on the road

Each point is one registration cohort. Older cars on the left, newer on the right. A flatter line means the model holds up over time; a steep drop means cohorts disappear from UK roads faster.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Bentley Bentayga, or your exact vehicle, has any outstanding recalls on the official DVSA service.

Check on GOV.UK

Opens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.

Theft risk

A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.

Whole-car theft

Higher

Desirable SUVs like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.

Parts theft

Around average

Parts-theft risk is around average — catalytic-converter theft is the main thing to be aware of on any petrol or diesel car.

Worth doing

Keep keys in a Faraday pouch and away from the front door to block relay attacks.
A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.

Clean-air zones

Whether driving a Bentley Bentayga into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.

Charging zones for cars

City	Area	Daily charge	Likely outcome
London	All of Greater London (within the M25)	£12.50	Likely exempt Petrol from 2006 meets Euro 4.
Birmingham	Inside the A4540 Middleway	£8.00	Likely exempt Petrol from 2006 meets Euro 4.

For context, the UK has roughly 4,500 franchised car-dealer outlets in total, plus about 15,500 independent garages.
