🔍 Model Background

The Mercedes 300 CD (1981) was a luxurious and refined two-door coupe based on the W123 platform, offering a stylish combination of performance, comfort, and classic Mercedes-Benz engineering. It was part of the W123 series, one of Mercedes-Benz's most enduring and successful models, known for its durability and timeless appeal.

The 300 CD was known for its reliable diesel powertrain, making it a preferred choice for long-distance cruising and daily driving alike.

Built on the robust W123 chassis, the 300 CD featured independent suspension, power-assisted brakes, and solid engineering that ensured a comfortable, stable ride. The coupe's design was elegant, with a sloping roofline and distinctive lines that gave it a dynamic, yet refined presence on the road. The W123 platform was also known for its safety features, such as reinforced side-impact protection and crumple zones, making it a safe choice for drivers and passengers alike.

Inside, the 300 CD offered a spacious and luxurious cabin, with premium upholstery, high-quality materials, and ample comfort features for its time. The interior included leather or MB-Tex seating, power windows, air conditioning, and a well-appointed dashboard that emphasized simplicity and elegance.
