1978 was Cadillac's last year for the large Eldorado. To commemorate this, Cadillac made a very limited production called the "Eldorado Custom Biarritz Classic". This special build of only 2,000 total units was announced to Cadillac dealers in April of 1978 and was produced between May and July of 1978. The "Eldorado Classic" shared all of the special features of the Custom Biarritz, plus the following distinct additions: Unique two tone exterior of Arizona Beige and Demitasse Brown, dark brown Biarritz-style accent striping, light beige interior trim with dark Saddle leather "pillowed" seat cushion and back rests, light beige Elk Grain Cabriolet-style vinyl half roof, gold-plated Biarritz scripts on the sail panels and deck lid, leather-wrapped steering wheel and color-matched wheel discs.
