The "Riviera trim", as it was initially called, was made available on the Roadmaster convertible very late in the '49 model year. It proved so popular that by the 1951 model year, it was made a standard feature on all Buicks. On 1950s models with two-tone paint, the Sweepspear separated the two colors.
