A Luxury Upgrade of the W111 "Fintail" The Mercedes-Benz 300SE (W112) was introduced in 1961 as a more luxurious and powerful version of the W111 "Fintail" sedan, featuring high-end materials and advanced technology.
Equipped with a 3.0L M189 Inline-Six Engine The 300SE was powered by a 3.0-liter M189 inline-six engine, producing 160 horsepower (later upgraded to 170 hp), providing smooth and refined performance.
First Mercedes with Standard Air Suspension Unlike the W111, the W112 came standard with self-leveling air suspension, a feature previously seen only on ultra-luxury cars like the Rolls-Royce Silver Cloud.
Expensive and Exclusive for Its Time The 300SE was one of the most expensive Mercedes models of the 1960s, costing significantly more than the standard W111, making it a car for wealthy buyers and diplomats.
Handcrafted Interior with Premium Materials The cabin was adorned with real wood trim, leather upholstery, and high-quality chrome accents, ensuring a luxurious driving experience.
Available as a Coupe and Cabriolet In addition to the four-door sedan, the 300SE was also available in two-door coupe and convertible (Cabriolet) versions, making it one of the most elegant cars of its era.
Four-Speed Automatic Transmission as Standard The 300SE featured a four-speed automatic transmission as standard, a rarity for the time, though a four-speed manual option was still available.
Advanced Safety Features for the 1960s The 300SE came equipped with four-wheel disc brakes, crumple zones, and a rigid passenger cell, making it one of the safest sedans of its time.
Limited Production Numbers Due to its high price, fewer than 6,800 units of the 300SE sedan were built between 1961 and 1967, making it a rare and collectible classic.
A Classic Mercedes with Rising Value Due to its engineering excellence, luxury, and historical significance, the Mercedes-Benz 300SE W112 has become highly collectible, with well-preserved examples appreciating in value.

The W112 300SE is a rare hand-built luxury sedan with air suspension, fuel injection, and 3.0L M189 inline-six (160hp). A "Fintail" aristocrat that predates the S-Class—now a coveted barn find or concours queen.
