2018 Bentley Continental GT 6.0L Petrol · Y9 GSE

The Bentley Continental GT presents a mixed but ultimately concerning maintenance history, with its most recent MOT in December 2025 showing no defects at 36,457 miles—a clean pass that suggests the vehicle met all roadworthiness standards at the time. However, the trend is not stable. The February 2024 failure at just 25,111 miles reveals a critical oversight: a continuous oil leak from the engine, classified as a serious risk, alongside a near-legal-limit tyre on the nearside rear. This failure was followed by two consecutive passes in February and December 2024, with no further defects recorded, implying the oil leak and tyre issues were addressed—but whether permanently remains unverified. The absence of defects in the 2023 and 2025 tests suggests intermittent compliance rather than consistent upkeep, particularly given the high-value nature of this vehicle. Mileage accumulation is unusually low for its age, averaging around 4,557 miles per year, which may indicate infrequent use or prolonged storage periods. The gap between the 2023 test (18,350 miles) and the 2024 failure (25,111 miles) covers just 10 months but shows a sudden 6,761-mile jump—a relatively rapid increase for a vehicle of this class. The subsequent 5,494-mile rise between February and December 2024 suggests sporadic but not excessive driving. The most recent 5,852-mile interval between December 2024 and December 2025 aligns with the prior pattern, though the lack of defects in the latest test does not guarantee the underlying issues have been fully resolved. For a prospective buyer, the primary red flags demand immediate attention. The February 2024 oil leak—if not properly repaired—could lead to catastrophic engine damage, so verification of the fix is essential. Inspect the engine bay for residual oil stains, check oil levels between tests, and confirm the source of the leak was identified and rectified. The near-legal-limit tyre, combined with edge wear, suggests either aggressive driving or neglect; examine all four tyres for uneven wear, tread depth, and sidewall integrity. Given the Bentley’s suspension and braking systems are typically robust but high-maintenance, a thorough check of coil springs, anti-roll bars, and brake calipers for binding or corrosion is advisable. Structural corrosion, while not mentioned, should be scrutinised in high-stress areas like sills and wheel arches, particularly if the vehicle has been stored in damp conditions. The absence of recent advisories does not eliminate the need for a pre-purchase inspection by a specialist familiar with luxury GT models.
