1958 Plymouth Belvedere: 1957 would be a banner year for the Chrysler Corporation, and Plymouth was no exception. Plymouth's design was so revolutionary that Chrysler used the slogan "Suddenly, it's 1960!" to promote the new car. The Belvedere line once again included the Fury. This year a new 318 in3 V8 with dual four-barrel carburetors was the standard engine in the Fury, and it was available on all Plymouths.
The Belvedere would once again return as a top level trim for 1958. Styling was evolutionary from the sleek 1957 models. Quad headlights were new, as was a big block 350 in3 V8 with dual four-barrel carburetors dubbed "Golden Commando" optional on all models.
The convertible was only available in the Belvedere model between 1956 and 1958.
