1990model  Mercedes-Benz W124 300TE (Early Model)

Solid, dignified, and deeply captivating… simply hearing the sound of the doors opening and closing on this W124 300TE brings an involuntary smile.

As I settle into the well-preserved black leather seats—still in excellent condition—I savor the subtle sensation of compressed air moving through the cabin.

Having owned and driven four W123s over more than 20 years, my first impression upon sitting in this early-model W124 was the remarkably body-friendly seat design. Combined with the supple quality of the leather, it is enough to move any classic Mercedes enthusiast to tears. And so, this interview began.

Unfortunately, as the vehicle inspection expired in June 2021, we were unable to take it out from the owner’s beautifully appointed villa garage. Yet this 1990 early-model W124 300TE—carefully stored and started regularly—stood before me as a testament to late-1980s design evolution and modernization. The refined instrument cluster left a strong impression, and the moment the ignition turned, it began telling a story—of an owner’s devotion and of years of careful maturation alongside a master mechanic who knows this model intimately.

The seasoned owner, well-versed in European classics ranging from aggressive sports cars to refined sedans, told me something particularly striking: before acquiring this W124, he did not first search for the car—but for a mechanic deeply knowledgeable in W124s.

He believed that truly enjoying a neo-classic Mercedes in its authentic form is not simply about purchasing the vehicle itself, but about the relationship with the person entrusted to maintain it.

That journey led him to a Mercedes specialist shop in Kanagawa—“FACT”—and to Mr. Kobayashi, a craftsman regarded as a master of the W124.

Before purchasing this 300TE, the owner consulted Mr. Kobayashi about what kind of example to select. The advice was clear and concise:
Left-hand drive. Leather seats. Sunroof.

With those three elements in place, the car would be recognized as properly valuable—not only in Japan but also by enthusiasts in Germany and abroad—provided it was carefully matured over time.

Guided by that advice, the owner began searching for a suitable example.

Fate works in mysterious ways. Astonishingly, a car meeting those criteria was found just a few hundred meters from the owner’s residence. After negotiations, he acquired it. Though fundamentally sound, the car did not yet possess the dignified appearance it now carries. It wore AMG-style bumpers and other non-original embellishments.

The owner painstakingly returned each element to factory specification, restoring the authentic character of the early W124. His philosophy was simple: respect originality and savor the essence of the W124 300TE itself.

And then there is the other indispensable element of this story—
Thirteen years of meticulously recorded maintenance history.

Fuel pumps. Engine mounts. Brakes. Suspension. ATF changes. Cylinder head overhaul…

By understanding the potential issues common to the W124 and addressing them proactively—including preventive maintenance—the owner ensured that the car’s original character could always be enjoyed.

This is precisely how European enthusiasts treat their beloved cars—like members of the family—investing time and energy into thoughtful upgrades and preservation. Over thirteen years, the owner faced occasional issues, embraced them, and overcame them with enthusiasm. That journey itself became part of this car’s story.

One particularly memorable anecdote involved an idle instability issue.

Suspecting the fuel system, the injectors were replaced—yet the issue persisted. Electrical components were examined next, but still no resolution. Ultimately, the cause was traced to voltage drop due to deterioration of the main battery cable.

Anyone who understands older Mercedes models will surely nod in recognition at this tale.

Additionally, the well-known single-wiper gear issue—a common W124 weak point—has been addressed with the updated aluminum component, replacing the original plastic gear that inevitably fails with age.

Reviewing the maintenance records page by page, it becomes clear that this car has been nurtured and matured through the collaboration of a passionate owner and a master mechanic deeply familiar with the W124.

Toward the end of the interview, one comment lingered in my heart:
“This car doesn’t make you tired at all, even on long journeys.”

He recounted a 1,200 km round-trip drive to the Kumano Kodo with a friend. Both were astonished at how little fatigue they felt.

The reason lies not only in the seats, but in the body rigidity and engine characteristics. The atmosphere and over-engineered functionality of the W124 achieve a perfect balance. There is a sense of being protected by the car’s structural integrity—a quality truly special to this era of Mercedes-Benz.

The 13 years of maintenance have been carefully logged in Excel. A chronological summary reveals the breadth of work performed—from engine overhauls and fuel system replacements to brake, suspension, transmission, and climate system servicing.

At approximately 190,000 km, the instrument cluster was replaced. The current indicated mileage is 225,000 km, reflecting actual mileage.

Across all systems—engine, fuel, intake, cooling, electrical, brakes, suspension, exhaust, transmission, air conditioning, tires—the car has received thorough and attentive care.

It is clear that this W124 300TE has been comprehensively maintained.

Owning a neo-classic is not about reaching completion at the moment of purchase. True enthusiasts understand that ownership is the beginning—a process of gradual refinement, deeper understanding, and careful maturation toward one’s ideal vision.

This 1990 W124 300TE represents exactly that journey—thirteen ideal years during which the owner carefully enjoyed and cultivated the car to its present, beautifully matured state.
