The W124 gained a good reputation for reliability. In 1995 the diesel engined version topped the "upper middle class" category in a reliability survey of 4-6 year old cars undertaken by the German Automobile Association (ADAC), with 11.8 recorded breakdowns per 1,000 vehicles for four year old cars and 21.6 for six year old ones: this compared with 14.6 breakdowns per 1,000 cars for four year old Audi 100s and 27.3 for six year old big Audis.
The W124 is a mid-sized vehicle platform. Due to the high cost of German engineering and build quality, the W124 was designed to last many miles, with awards actually given and worn by high mileage versions.
Front suspension uses a separate spring and damper with a rubber top mount. The rear suspension of the W124 features the Mercedes multi-link axle introduced in 1982 with the Mercedes 190 and which is now standard on many modern cars. Estate cars (and optionally, saloons and coupes) had Citroen-like self-leveling rear suspension with suspension struts rather than shock absorbers, gas-filled suspension spheres to provide damping and an under bonnet pressurizing pump. Unlike the traditional Citroën application Mercedes opted for a fixed ride height and employed rear coil springs to maintain the static ride height when parked.
The R129 was based on the W124 platform, in return W124 was equipped with one of the roadster's engines, in its 500E version..
Much of the 124's engineering and many of its features were advanced automotive technology at its introduction, incorporating innovations that have been adopted throughout the industry.[4] It had one of the lowest coefficient of drag (Cd) of any vehicle of the time (0.28 for the 200/200D model for the European market with 185/65 R15 tires) due to its aerodynamic body, that included plastic molding for the undercarriage to streamline airflow beneath the car, reducing fuel consumption and wind noise. It had a single windscreen wiper that had an eccentric mechanism at its base that extended the wiper's reach to the top corners of the windscreen (more than if it had traveled in a simple arc). The saloon/sedan, coupés and convertibles had optional rear headrests that would fold down remotely to improve rearward visibility when required. This feature was not available for the T-model because of its specific layout (no space to store the retractable headrests), but the station-wagon serially came with a "neighbour-friendly" rear door that was pulled in the shut-position silently and automatically by a sensor-controlled servomotor. With the exception of the 200, which was equipped with a Stromberg or Pierburg carburetor but was not available to the United States, fuel injection was standard, and the engines incorporated features that maximised performance. The most notable such feature was the addition of an oxygen sensor in the exhaust system which, in conjunction with a semi-electronic fuel injection system, could make the engine run more efficiently. This improved fuel consumption while simultaneously meeting stricter emission regulations. Mercedes-Benz's four-wheel drive system, the 4Matic was first introduced on the W124 in 1986.

Plot twist;
This car isnt even turned on.
Sound is actually from the OM603 car next to it.

That’s a proper Diesle none of this ad blue dpf shit that engine will still be running in 20 years when all. The new shit will be scrap

[MissionaryForMexico]

The trick? Is to have new engine motor mounts! I own a 1983 300SD.

[Suberten]

der is niets zo fijn als een 6 in lijn!

[mkdriver]

hehe, natuurlijk blijft dat staan, nu met een euromunt op z'n kant.

breakdowns on 4-6 year old cars? not so good.
