• Engine: Options ranged from efficient diesel engines to the renowned inline-six M103 and M104, with the AMG versions offering exhilarating power.
• Suspension: The W124 offered an adjustable ride height, setting the foundation for today's adaptive suspension systems.

Examples:

• A 1986 300D is known for surpassing one million miles, demonstrating the longevity and reliability of the W124.

Tips for W124 Owners:

• Regularly check the rear subframe for signs of rust as it's a common issue due to exposure to road grime.
