The C110 generation was produced from 1972 through 1977. For export in the 1970s, the C110 and GC110 Skyline was sold as the Datsun K-series, with models such as the Datsun 160K, 180K and Datsun 240K. Its appearance seems to be influenced by the 1970–1975 Citroën SM. The styling also influenced a smaller, more affordable two-door coupe, called the Silvia. The C110 Skyline was better known as the "Ken & Mary" or "Kenmeri" (ケンメリ) Skyline, stemming from the advertisement campaign in Japan at the time which featured a young couple (Ken and Mary) who relaxed and enjoyed the countryside in Ken and Mary's Skyline (ケンとメリーのスカイライン). The ads were highly successful and perhaps as a result the C110 was sold in very large numbers in Japan. Kenmeri was also a play on the term "Meriken" (メリケン) an old Japanese slang term for "American" due to the new Skyline's resemblance of American muscle cars of the time.
