At the beginning of 1954, Buick Dealers were guided by Buick, to allow some colors only to Riviera and Convertible models. During the year, Buick dropped this limitation. The colors here are showing the late color availabilities. Two-Tone paint was at extra cost. In this case, only the roof could be painted differently. Note: Color accuracy varies by computer/device settings and depends on the actual light.
