Mercedes-Benz 300SE: A Year-by-Year Breakdown
| Year(s) | Model Specifics | Key Considerations |
|---|---|---|
| 1961-1965 (W111 "Fintail") | Original "Fintail" design; M189 3.0L inline-six engine; Available with air suspension (often problematic); Early models may have carburetors (less desirable); Later models fuel injection (more desirable); Wood trim and leather interiors typical. | Rust: W111s are prone to rust, especially in lower body panels, around the headlights, and wheel arches. Air Suspension: If equipped, the air suspension is complex and expensive to maintain. Engine Condition: Check for proper maintenance records and compression. Interior Condition: Look for wear and tear on the wood trim and leather. Carbureted vs. Fuel Injected: Fuel injection provides better performance and reliability. |
| 1966-1967 (W109) | Long-wheelbase version of the W108; Generally considered more luxurious than the W111; M189 3.0L inline-six engine; Available with air suspension (often problematic); Improved build quality compared to earlier models; More spacious interior. | Rust: Still a concern, but generally less prevalent than on the W111. Air Suspension: Same maintenance concerns as the W111. Higher Price: W109s typically command a higher price due to their rarity and luxury. Parts Availability: Some parts may be more difficult to source than for the W111. Overall Condition: Given their age, thorough inspection is crucial. |
| 1968-1972 (W108/W109) | Revisions to styling and mechanicals; Introduction of the M130 2.8L inline-six engine (some markets); Improved automatic transmissions; Power windows and air conditioning more common; Minor cosmetic changes. | Engine Choice: The 2.8L engine is generally considered more reliable and easier to maintain than the earlier 3.0L. Transmission Condition: Check for smooth shifting and proper operation of the automatic transmission. Electrical Issues: As with any older car, electrical issues can arise. Rust: Still a factor, but later models are typically better protected. Aftermarket Support: Good aftermarket support for common parts. |
Detailed Explanations
1961-1965 (W111 "Fintail"): These models represent the classic "Fintail" design, a hallmark of Mercedes-Benz styling in the early 1960s. They are powered by the M189 3.0L inline-six engine, which can be found with either carburetors or fuel injection. The early carbureted versions are generally less desirable due to their lower performance and increased maintenance requirements. The W111s are known for their elegant interiors featuring wood trim and leather. However, they are also prone to rust, particularly in the lower body panels. The optional air suspension, while offering a luxurious ride, is notoriously complex and expensive to repair, making it a potential source of headaches.
1966-1967 (W109): The W109 is a long-wheelbase version of the W108 sedan, offering a more spacious and luxurious experience. It shares the M189 3.0L inline-six engine with the later W111 models. While it retains the air suspension option, the W109 generally benefits from improved build quality compared to its predecessor. The added length translates to more legroom and a more comfortable ride for rear passengers. Due to their rarity and enhanced luxury, W109s typically command a higher price on the classic car market.
1968-1972 (W108/W109): These later models saw revisions to the styling and mechanicals of the 300SE. A significant change was the introduction of the M130 2.8L inline-six engine in some markets, considered by many to be more reliable and easier to maintain than the earlier 3.0L. The automatic transmissions were also improved during this period. Power windows and air conditioning became more common options, adding to the comfort and convenience. While rust remained a concern, later models were generally better protected against corrosion. The availability of aftermarket parts for these models is generally good, making maintenance and repairs easier.
