The Bentley S3: A Comprehensive Guide for Discerning Buyers
The Bentley S3 represents the pinnacle of pre-war engineering refinement elegantly melded with post-war luxury. It is a full-size luxury car produced by Bentley from 1962 to 1965. Building upon the successful S2, the S3 offered improved performance, updated styling, and the renowned Bentley commitment to craftsmanship, solidifying its place as a highly desirable classic.
Generations
The Bentley S series represents an evolution rather than a radical departure. As such, the S3 doesn't have distinct "generations" in the way modern cars do. Instead, it represents the third iteration in the series, building on the strengths of its predecessors with subtle but significant improvements.
- Bentley S1 (1955-1959): The foundation of the S series, introducing the all-new body style after the pre-war designs. Straight-six engine (later replaced by a V8).
- Bentley S2 (1959-1962): Marked a significant upgrade with the introduction of the all-aluminum 6.2-liter V8 engine. Improved performance and refinement.
- Bentley S3 (1962-1965): The final iteration of the series. Key changes included:
- Quad headlamps, giving a more modern and aggressive look.
- Revised interior, often featuring improved materials and layouts.
- Improved braking system in later models.
Reliability & Common Issues
Owning a Bentley S3 is a rewarding experience, but potential buyers should be aware of common issues. These cars are mechanically complex and require specialist knowledge to maintain. A thorough pre-purchase inspection by a qualified mechanic familiar with these vehicles is essential.
Engine (6.2-liter V8):
- Overheating: The aluminum V8 can be prone to overheating, especially if the cooling system is not properly maintained. Check for leaks, ensure the radiator is clean, and verify the thermostat and water pump are functioning correctly. Blocked waterways are common after periods of disuse.
- Oil Leaks: These engines are known for oil leaks. Common sources include valve covers, front and rear crankshaft seals, and the oil pan gasket. Leaks can be messy but are usually manageable with proper maintenance.
- Carburetor Issues: The twin SU carburetors require regular tuning and maintenance to ensure smooth running. Incorrect mixtures can lead to poor performance, fuel consumption, and emissions. Specialist tuning is often needed to optimise performance.
- Valve train issues: The complex valve train can be noisy, and the tappets require regular adjustment. Worn camshafts and followers are a possibility on high-mileage examples.
Transmission (Automatic):
- Gearbox Problems: The automatic transmission, usually a GM Hydramatic, is generally reliable but can suffer from wear and tear over time. Look for smooth gear changes and listen for any unusual noises. Servicing at regular intervals is a must. Delayed or harsh shifting is a bad sign.
Suspension & Brakes:
- Suspension: The sophisticated suspension system, including hydraulic self-leveling on the rear, requires specialized attention. Check for leaks in the hydraulic lines and ensure the system is functioning correctly. Bushings and ball joints are prone to wear.
- Brakes: The braking system can be complex and requires regular maintenance. Look for fluid leaks and ensure the brakes are functioning properly. The early S3 models had a less powerful system. Late-production examples benefited from improvements. Inspect brake lines for corrosion.
Electrical System:
- Wiring Issues: The Lucas electrical system, while improved from earlier British cars, can still be problematic. Look for brittle or damaged wiring, especially around the engine compartment. Corrosion in connectors can cause issues. An overhaul may be necessary.
Body & Trim:
- Corrosion: Rust can be a significant issue, especially in areas prone to moisture. Check the floor pans, sills, wheel arches, and door bottoms. Bodywork repairs can be very costly.
- Trim Condition: Interior trim, including leather, wood, and chrome, can deteriorate over time. Restoring these components can be expensive. Ensure all trim pieces are present and in reasonable condition.
Driving Experience
Driving a Bentley S3 is an experience unlike any other. It's a stately and luxurious ride, offering a comfortable and refined driving experience. However, it's important to remember that this is a classic car, and it won't perform like a modern vehicle.
Pros:
- Luxury and Comfort: The S3 offers unparalleled luxury and comfort, with plush leather seats, rich wood trim, and a smooth, quiet ride.
- Effortless Power: The 6.2-liter V8 engine provides ample power for comfortable cruising.
- Head-Turning Style: The S3's elegant and distinctive styling is sure to turn heads wherever you go.
- Unique Driving Experience: It offers a connection to a bygone era of motoring that cannot be replicated in modern cars.
Cons:
- Running Costs: Owning an S3 can be expensive due to maintenance, repairs, and fuel consumption.
- Handling: While comfortable, the S3 is not a sports car. Handling is soft and forgiving, but not particularly sporty.
- Reliability: As with any classic car, reliability can be an issue. Regular maintenance and repairs are essential.
- Size: The S3 is a large car, making it difficult to maneuver in tight spaces.
Buying Advice
Purchasing a Bentley S3 requires careful consideration. Here are some tips to help you find the right car:
What to Look For:
- Comprehensive Service History: Look for a car with a detailed service history, demonstrating regular maintenance and repairs.
- Originality: Original cars are generally more desirable and valuable. Check for original trim, paint, and mechanical components.
- Rust-Free Example: Prioritize cars with minimal rust. Extensive rust repair can be costly and time-consuming.
- Late-Production Models (1964-1965): These models often benefited from improvements, particularly in the braking system.
What to Avoid:
- Cars with Significant Rust: Avoid cars with extensive rust damage, as repairs can be prohibitively expensive.
- Cars with Poorly Documented History: A lack of service history can be a red flag. It's important to know the car's maintenance history.
- Cars with Extensive Modifications: While some modifications may be acceptable, excessive alterations can detract from the car's value and originality.
- Cars that have been standing for a long period of time with no use: Many problems will surface when the car is put back into use after a long period of disuse.
Years to Consider:
- All S3 years (1962-1965) are desirable, but later production models are generally considered more refined. Focus on overall condition and maintenance history rather than solely on the year.
Final Thoughts:
The Bentley S3 is a magnificent classic car that offers a unique blend of luxury, style, and performance. With careful research, diligent inspection, and a commitment to ongoing maintenance, you can enjoy the rewarding experience of owning and driving this iconic vehicle.
