16: Landau/Vinyl Roofs
At the time, Landau roofs were considered the ultimate pinnacle of American luxury, but most consumers weren’t looking at the long-term negatives. For starters, these roofs would deteriorate and fall apart with age. This is the case with many different types of vinyl which includes convertible tops. Thus, most of the cars that had a Landau roof didn’t last the test of time.

Replacing a vinyl roof can be an expensive proposition and not something that many people want to deal with. Unless you were a grandma, these roofs fell out of style by the ’90s, although you’ll still see a Landau roof on a modern Cadillac from time to time. But the style is something that went out a long time ago.
