Nissan Silvia: The Nissan Silvia is the name given to the company's long-running line of sport coupes based on the Nissan S platform.  Although recent models have shared this chassis with other vehicles produced by Nissan (most notably the European 200SX and North American 240SX in the S13 and S14 generations, and 180SX in the Japanese market), the name "Silvia" is not interchangeable with the chassis codes.  The Nissan Silvia's main competitors worldwide were the Honda Prelude, Mazda MX-6, Toyota Celica, Mitsubishi Eclipse, and Honda Integra.

During the initial year of this car, it evolved considerably.  The front fenders came in three pieces, the theory being that small damage could be replaced easily.  During the year, it evolved into two pieces with the lower front and back sections being joined.  The hood risers changed, the early ones being the same as 1940 Fords, changing during the year to the better later version.  The 1941 Convertible had no rear side windows, the only side windows being in the doors; in 1942, quarter windows were added so the rear occupants could see out.

Going a step further, the F-Series integrated the hood into the bodywork with a clamshell design; the feature would stay part of the F-Series for two decades.  Although offered previously, the optional chrome grille was far more prominent than before.  In the rear, two types of pickup boxes were offered, starting a new naming convention: the traditional separate-fender box was dubbed "FlareSide", while "StyleSide" boxes integrated the pickup bed, cab, and front fenders together.  As before, Ford still offered a "Low GVWR" version of each model.
