The Opel Manta was launched in 1970 and production of first generation cars like the one below stopped in 1975. Buick dealers sold Opels on the U.S. market and the Manta could be ordered with a 1600cc or a 1900cc.
Launched in 1961, the Renault Floride (or Caravelle in the U.S.) sat on a Dauphine platform and for better or worse used the Dauphine Gordini's Ventoux engine in 845cc form. The Renault 8's 1108cc replaced the Ventoux in 1965 and gave the Floride a much-needed boost in power. Production stopped in 1968. (As a side note, some early Renault 4s used a standard Dauphine engine bored out to 845cc; despite having the displacement they were different engines.)
