Best Answer

Regardless of which capacity engine is fitted, these W124 cars have stood up to hard work as few other European models have. The most common problem has been with the viscous fan coupling, which has been known to break down in traffic and lead to engine overheating. The fan repair costs upwards of $600, but any consequent engine damage will be dramatically dearer.

Barring such mishaps, the engine can be expected to last as long as the car and you could expect at least 300,000 km (and probably 500,000 km) in ordinary use. The other mechanical components are also very durable.

What to look for

Previous repairs: The worst news would be poor smash work. Check panels and chassis thoroughly.

Engine fan: Viscous coupling set-up can break down, leading to engine overheating.

Prices and details correct at publication.
