2017 Bentley Bentayga 4.0L Diesel · DEC 888

The 3956cc diesel engine is significantly more fuel-efficient than the petrol equivalent for high-mileage drivers, but expect around 25-30 mpg in real-world conditions. Tax will be high due to the large engine capacity, and insurance groups for this model are typically in the highest brackets.

Maintenance costs are the primary factor; a standard annual service at a specialist or dealer will command a premium price. You should budget a significant contingency fund for unexpected repairs, as components like air suspension compressors and electronic sensors are costly to replace as the vehicle ages further.

The MOT history is surprisingly clean, with no defects recorded even at 67,046 miles. However, you should manually inspect the air suspension for leaks; check if the car sags after being parked overnight, which can indicate leaking struts or compressors. Given the 2017 registration, also inspect the underbody for any signs of corrosion, despite the clean MOT results.

Pay close attention to the interior leather and trim for cracking or excessive wear, which would indicate if the car has been poorly maintained. Since it is a diesel, ensure the Diesel Particulate Filter (DPF) has been allowed to clear regularly by asking if the car has only been used for short city trips frequently.
