This 1977 Mercedes 450 SEL 6.9 has 57k original miles and is one of around 1,800 sold in the USA. It comes with comprehensive service records from new and is described as a clean and largely original example. The seller has owned it for three years after purchasing it from a past MBCA region president. Fast and expensive when new, these high-performance flagships often wound up neglected – but this one has been driven and maintained as needed throughout its life. Recent maintenance items include rebuilt steering gear, new suspension accumulator spheres, new A/C compressor, and more detailed below. The seller exercises the car regularly and has put about 2000 miles per year on it including a recent 700-mile round trip to Monterey.

Paint is a quality respray in the original color and is holding up well, with some chips evident and very minor rust bubbling around the edge of the sunroof. European market headlights and black Penta wheels are nice additions. The seller does a good job photographing detail below.

The blue leather interior has aged well, with all materials in very good shape for their age. The burled walnut veneer is holding up well, while slight wear is visible on the driver’s seat. The seller points out a cracked passenger-side door panel and tired padding in the back seat. Note the clean rear seats and front seat back. The automatic climate control system works blowing hot and cold air on command. The odometer stopped working this week but the seller will have it fixed before the new owner takes delivery. The 6.9’s namesake cast iron V8 featured aluminum heads, forged internals, and a dry-sump oiling system. Fed by K-Jet injection, in US form it produced 250 horsepower and 360 lb. ft. of torque when new. The engine is original and has never been opened for major repair. Other features include self-leveling, independent hydropneumatic suspension with driver-adjustable ride height, a three-speed automatic transmission, ZF limited slip differential and four-wheel disc brakes. All are in good operating condition.
