We have written a lot about the Mercedes W126 S-class (you know, when we get around to writing at all!), but for me that’s largely because they are among the best luxo-barges ever produced. Modern enough to offer an excellent driving experience, and old enough that they’re not entirely bogged-down with technology certain to strand you in some catastrophic symphony of warning lights. Besides, they are so completely logical in their engineering and design – my Dad always referred to his as fitting together like a Chinese puzzle – that even incompetent hack mechanics like me can wrench on them. This pretty 1985 500SEL in Fort Worth, Texas comes with a little bonus surprise of its own. There weren’t many options available on U.S. market cars, but this car has one of the coolest ones. Find it here on eBay with a buy it now price of $9,995 or best offer.
