Stepping in off the cobblestone street in Greenwich Village, the first car in the door at Cooper Classic Cars is a 3.5-liter Mercedes-Benz convertible. It is stately, almost plain for what it is, but exquisitely well-made. To an ordinary observer, it’s just an old Mercedes like any other. To a trained eye, it is a remarkably rare classic. Only produced from the end of 1969 to the start of 1971, it was the top-of-the-line V8 model from the peak moment for Mercedes quality. It is a high point, the end of an era.

“Do you know that car?” Elliot Cuker, owner and founder of Cooper Classic Cars asks from the lofted office overlooking the gallery-like space. “1971, only made for one year. They made 1,200 of them. I used to have three of them in this showroom. I still have one now.”

There was a time when these cars could be bought on the cheap. There was a time when they flew under the radar. But that time is gone. So strong of a cult following do these cars have that Mercedes started factory-restoring them. For close to $800,000 you can buy one completely overhauled from Brabus.

“At one point I was charging $200,000 for one,” Cuker says. “People said I should be committed.”
