Our Verdict
A rare, low-mileage example of a 1989 Be
The most striking pattern in the MOT history is the repeated mention of perishing tyres (recorded in 2022, 2024, and 2026). This is a strong indicator of a vehicle that has spent long periods without being driven, which can lead to other issues such as seized brake calipers or degraded rubber seals. Prioritise a review of the service history to see if the car was stored in a climate-controlled environment or exercised regularly between tests.
Negotiate based on the immediate need for new tyres and the potential need to replace the offside rear shock absorber, which has been flagged for oil misting in two separate tests. Given the complexity of the 6.75L engine, ensure any specialist maintenance has been documented, as the MOT history only confirms the vehicle's basic roadworthiness.
Running costs for a 6.75L petrol engine will be substantial. Fuel economy will be very low, and the vehicle will fall into a high tax bracket due to its engine size and age. Insurance for a classic Bentley usually requires a specialist provider, which can vary significantly based on the owner's profile.
Maintenance costs for this era of Bentley are typically high, requiring specialist knowledge and expensive parts. Between fuel, insurance, road tax, and the likely need for periodic specialist mechanical attention, annual costs will be significant.
Inspect all four tyres immediately, as the August 2026 MOT specifically noted them as perishing. Check the offside rear shock absorber for the oil misting reported in 2024 and 2026, and examine the front of the engine for the oil leak noted in the 2024 test to determine if it has progressed.
Given the evidence of low usage, check all rubber hoses, belts, and bushings for cracking or brittleness. It is also advisable to check the brake discs for surface corrosion and ensure the fuel system is free from varnish or deposits caused by long-term storage.
This blue 1989 Bentley Turbo has recorded 97,219 miles. The MOT history from 2022 to 2026 shows four passes, though it is flagged by recurring advisories regarding perishing tyres and a light oil leak. It offers a low-mileage entry into the 6.75L petrol engine range, provided the effects of low usage are addressed.
Aggregate MOT data is unavailable for the Bentley Turbo, making individual vehicle history the primary indicator of reliability.

- High-Pressure Hydraulic Brake Accumulator and Mineral Oil System FailureSerious
The Turbo R utilises a Citroën-licensed high-pressure dual-circuit hydraulic braking and self-levelling suspension system powered by two engine-driven mechanical pumps. Over time, the nitrogen-filled spherical brake accumulators lose their charge, internal seals in the brake distribution valves degrade, and corrosive mineral fluid (or incorrect DOT fluid mistakenly added) ruins the internal rubber seals. This causes rapid pedal stiffening, delayed braking assistance, and pump cavitation.
- Exhaust Manifold Cracking and Gasket Blow-ByModerate
The cast iron exhaust manifolds and heat-cycling gaskets on the turbocharged 6.75-litre V8 undergo intense thermal expansion and contraction cycles. The massive heat retained in the SZ engine bay causes the cast iron manifolds to warp or develop hairline fissures, while the copper-clad composite manifold gaskets burn through, creating sharp ticking exhaust leaks on cold startup that can damage cylinder head studs.
