When discussing automotive legends, the Mercedes-Benz W124 invariably enters the conversation. Produced between 1985 and 1995, this E-Class generation, which succeeded the beloved W123 and paved the way for the W210, forged an enviable reputation for itself. It was conceived as a solid, medium-sized vehicle, a testament to Mercedes' commitment to comprehensive development and engineering excellence, prioritising durability and comfort above all else. But in an era of ever-evolving automotive technology, the perennial question remains: Is a Mercedes W124 still a good car in today's world?
The W124's Enduring Legacy: Engineering Prowess
The W124 wasn't just another car; it was a statement. Mercedes-Benz poured an extraordinary amount of resources into its development, resulting in a vehicle often described as 'over-engineered'. This wasn't a flaw, but rather a design philosophy that aimed for ultimate longevity and reliability. Every component, from the intricate wiring systems to the robust chassis, was designed to withstand the test of time, far exceeding the typical lifespan of contemporary vehicles. This dedication to durability is a cornerstone of the W124's appeal.
Its predecessor, the W123, had already set a high bar for reliability, but the W124 refined this even further, embracing advanced technology without sacrificing the brand's core values. The result was a car that felt substantial, secure, and incredibly well-built, qualities that are often lacking in modern, lighter vehicles. The W124’s build quality translates directly into a driving experience that feels incredibly solid and reassuring, even decades after it rolled off the production line.
A Range to Suit Every Need: Saloon, Estate, Coupe, and Convertible
The W124 platform was incredibly versatile, offered in a variety of body styles to cater to different customer needs. The most common were the saloon (W124), but also popular were the spacious estate (S124), the elegant coupé (C124), and the rare and highly desirable convertible (A124). Each variant shared the same underlying principles of robust construction and refined engineering.
One notable feature, particularly on the estate models, was the self-levelling rear suspension. This innovative system, designed to maintain a constant ride height regardless of load, was remarkably similar in concept to that found on certain Citroën models, such as the BX. This attention to practical detail ensured that even when fully laden, the W124 estate maintained its composure and handling characteristics, making it an ideal vehicle for families and those needing ample cargo space without compromising ride quality.
Engine Choices: Reliable Powerhouses
Over its decade-long production run, the W124 was offered with a wide array of engines, both petrol and diesel, ranging from economical four-cylinders to powerful six-cylinder units, and later, even V8 engines in the E-Class guise. While not all were performance monsters, they were universally praised for their reliability and smooth operation. The diesel engines, in particular, gained legendary status for their ability to cover vast mileages with minimal fuss, often exceeding 500,000 miles with proper maintenance.
Common engine types included:
- Petrol: 2.0L (200E), 2.3L (230E), 2.6L (260E), 3.0L (300E), and later 2.2L (E220), 2.8L (E280), 3.2L (E320), and the powerful 4.2L (E420) and 5.0L (E500/400E) V8s.
- Diesel: 2.0L (200D), 2.5L (250D), and 3.0L (300D), including turbocharged variants.
These engines, combined with Mercedes' robust automatic or manual gearboxes, delivered a refined and comfortable driving experience, more focused on effortless cruising than outright speed.
The Driving Experience: Comfort and Composure
Driving a W124 is a unique experience that sets it apart from many modern cars. The ride quality is exceptionally smooth, absorbing road imperfections with remarkable ease, a trait that contributes significantly to its reputation for comfort. The steering, while perhaps lacking the razor-sharp precision of a modern sports saloon, is well-weighted and reassuring, providing excellent stability at speed.
The interior, though dated by contemporary standards, is a masterclass in ergonomic design and quality materials. The seats are supportive and comfortable, perfect for long journeys, and the controls are logically laid out and built to last. There’s a distinct absence of flimsy plastics or rattling components, a testament to the meticulous attention to detail during its construction. It’s a car that truly feels like it was built to last, providing a serene and composed environment for its occupants.
Maintenance and Common Considerations
While the W124 is renowned for its durability, it's still an older vehicle, and like any classic, it requires diligent maintenance. Parts availability is generally good, thanks to a strong enthusiast community and Mercedes' excellent classic parts programme. However, some specific components, particularly for less common variants or later models with more complex electronics, can be harder to source or more expensive.
Common areas to inspect on a W124 include:
- Rust: While generally well-protected, areas like wheel arches, jacking points, and front wings can suffer, especially in the UK's damp climate.
- Wiring Harnesses: Later models (from around 1993 onwards) used a biodegradable wiring insulation that can degrade, leading to electrical issues. This is a known issue and requires attention. This is where resources like Mercedes W124 Wiring Diagrams become invaluable for diagnosis and repair.
- Automatic Gearbox: Generally robust, but ensure smooth shifts and regular fluid changes.
- Self-Levelling Suspension (SLS): On estate models, check for leaks or signs of system failure, as repairs can be costly.
- Vacuum Leaks: Can affect engine performance and various interior functions.
Owning a W124 is not necessarily cheap, but it represents excellent value for money compared to a new car. Fuel economy can be modest, especially with the larger petrol engines, and insurance for a classic can vary. However, the joy of driving and maintaining such a well-engineered machine often outweighs these costs for enthusiasts.
W124 Pros and Cons: A Balanced View
To summarise the W124's standing, here's a quick overview:
| Pros | Cons |
|---|---|
| Legendary build quality and reliability | Can be expensive to repair specific issues (e.g., wiring harness) |
| Exceptional ride comfort and refinement | Fuel economy can be poor on larger engine models |
| Timeless, elegant design | Rust can be an issue if not properly maintained |
