2007 Bentley Arnage 6.8L Petrol · XIG 4

Running costs for this Bentley will be exceptionally high. The 6.8L petrol engine will result in significant fuel consumption, likely requiring a high budget for petrol. Tax bands for a vehicle of this engine capacity are typically at the highest level, and insurance groups for luxury marquees like Bentley are predictably substantial.

Maintenance costs are expected to be significantly higher than a standard premium vehicle. While the MOT history shows minimal defects, the cost of parts and specialist labour for an Arnage can be extreme. An estimated annual budget should account for high fuel usage, premium insurance, and a substantial contingency fund for mechanical upkeep.

A physical inspection should pay close attention to the suspension components. The most recent MOT in July 2026 noted a severely deteriorated nearside front upper suspension arm ball joint dust cover; check that this has been replaced with high-quality parts and that no further deterioration is visible.

Additionally, inspect the condition of all rubber seals and bushings, as the vehicle's age may lead to perishing, even with low mileage. Given the large engine displacement, check for any signs of fluid leaks around the engine bay and ensure the cooling system is in good order, as large-capacity engines are sensitive to thermal management.
