The reliable models in the Mercedes Benz line-up are listed in the table below.

Mercedes Benz SL1989–2002R129
Mercedes Benz C Class1993-200W202

Mercedes Benz cars manufactured in the 1990s had good built quality and the company used materials like vinyl to make the interior more durable than standard leather. Vehicle modes were also made mostly from steel which made them slightly heavier but also very durable. The multiple layers of paint and steel chassis gave Mercedes Benz excellent corrosion resistance.

Mercedes Benz made many different models in the 1990s and shipped them to the international markets but the following three models became famous for their reliability:

Mercedes Benz E Class 

The Mercedes Benz E class launched in 1993 is a facelift model of the first generation of W 124 launched in 1984. The exterior styling mostly remained unchanged but it was the first W124 that was branded as E class. 

The Mercedes Benz E class was powered by reliable petrol and diesel engines. The four-cylinder diesel engines were also very fuel-efficient, the pre-glow system was capable of heating the combustion chamber even after the engine was started. The petrol engines were mostly known for their performance. The E class had inline 6 cylinder and V8 petrol engines that made 250-330 horsepower. 

The E class was available in different body styles like the estate and soft-top convertible roadster but it was the 4-door sedan model that became most popular.

Mercedes Benz SL

The Mercedes Benz SL model series R129 is a two-door convertible roadster model manufactured in the 1990s. It was the first convertible roadster model with a hydraulically folding Vario roof and automatic active c anti-roll bars. The anti-roll bars were designed to withstand the force of any accidental impact and even protect the occupants if the vehicle overturns.

The Vario roof system was very reliable and it can fold the hardtop off at a press of a button. The SL was based on a slightly shorter platform than the W124. It has inline 6 V8 and V12 engine options with a choice of 5-speed manual and 4-5 speed automatic gearbox.

Mercedes Benz C Class

The Mercedes Benz C Class model series W202 launched in 1993 was known as the first Mercedes Benz C class. It was the most reasonable car in the Mercedes Benz lineup. The C class W202 had the same engines as the W124. 

The electrical systems were updated and Mercedes Ben also debuted its second generation of the drive authorization system Das 2b. The Drive authorization system has an immobiliser that made the C class the most difficult car to steal.

Remote locking and unlocking were not available as standard, it used the infrared signal from the transmitter key and red and green LED lights in the door handle and rearview mirror to indicate the status of the immobiliser system. 

What is the reason for the great reliability of the 1990s Mercedes Benz models?

Following are the reasons for the reliability of the 1990s Mercedes Benz models:

  • Simple design

The 1990s models were so well engineered that an additional mechanical setup was required. All the models were front-engine rear-wheel drive. The engine was connected to the chassis by very durable engine mounts. The majority of models used independent systems on each wheel, the suspension system was made up of a double-wishbone with independent springs and shock absorbers.

Onboard electrical systems were very limited, the SL had a slow-speed CAN network which was capable of operating even on a single wire mode. Most of the control units were made up of mechanical relays and analogue circuits which were simple in design and lasted very long without any electrical faults.

  • Durable engines

Mercedes Benz used  M111 M112 petrol engines and OM601/ OM611 diesel engines in the 1990s models. These engines were very durable and offered great performance, there were no major reliability issues in the engines. Camshafts were housed in the cylinder heads and driven by a mechanical timing chain. 

The fuel pump and the fuel injectors in the diesel engines were Mechanical and did not require additional control units for pressure regulation. The fuel pump was driven by the timing chain and the fuel heater ensured Diesel is in liquid form before injection into the precombustion chamber. The diesel engines were more fuel economy compared to petrol and met emission requirements in various international markets till 1999.

Should you buy a 1990s Mercedes Benz in 2022?

Mercedes Benz models like E class and C class manufactured in the 1990s are very good cars but in 2022 they are neither considered classic nor exotic cars. The prices in the used car market are also low as  1990s models were mass-produced.

The Mercedes Benz SL 600 is the only 1990 car with a Mercedes Benz V12 engine and a 5-speed manual gearbox, it is the only car worth buying. Spare parts are easily available and there are plenty of local workshops specialised in restoring Mercedes Benz SL. The Vario roof system can develop hydraulic leaks but replacing the leaking cylinder is not expensive.
