The modern version of this market segment was successfully established in 1950 when "the Nash Rambler was deliberately conceived as a luxury compact rather than an austerity model" and available only as a convertible, with hardtop (no "B-pillar") and station wagon and models added in 1951 [REF].
Cadillac continued its sales leadership in the premium market by making changes with the market and introduced the 1982 Cadillac Cimarron, a luxury version of the compact GM J platform [REF].
