There is a reason why Jay Leno calls the W109 6.3 his favorite Mercedes-Benz. It’s a classic Mercedes design both inside and out then finished off with the M100 6.3 liter V8 that still holds it own with modern cars. It’s what a Mercedes-Benz should be. Don’t get me wrong, I love the new super AMG cars that have 650 horsepower and can drive themselves down the road, but you can get that from any brand now. In 1969, this was the car if you wanted a European super sedan. Not to mention you paid for it too at over $14,000, which was only a few thousand less than a Rolls-Royce Silver Shadow. But the Silver Shadow didn’t compare to the 6.3 in terms of power, build quality and reliability. That’s why this car still has a huge following and even higher demand to this day. So let’s check out this 1969 for sale in Massachusetts.
