10 Biggest American Land Yachts of the 1970s That Defined Excess

Biggest American land yachts of the 1970s: If you think today’s SUVs are big, wait until you see what Detroit was building in the 1970s. This was the golden age of American land yachts—massive cars with engines the size of small houses, interiors that looked like living rooms, and more chrome than you could polish in a weekend.

• 4,200 pounds in weight

Final Thought

These land yachts from the 1970s were statement pieces rather than merely cars. They were ostentatious, overbearing and massive, reflecting a uniquely American definition of luxury. These days they serve as sentimental reminders of a time when comfort was valued more highly than fuel economy.

You are fortunate to be seeing one of the last real titans of American motoring if you see one driving along the highway today.
