C4 Corvette 

The C4 Corvette was made from 1984-1996.  Due to economic challenges of the time the world was not graced with a 1983 model year of the Corvette.  Production was to begin for the 1983 model year but quality issues and part delays resulted in only 43 prototypes for the 1983 model year being produced that were never sold. All of the 1983 prototypes were destroyed or serialized to 1984 except one with a white exterior, medium blue interior, L83 350 ci, 205 bhp V8, and 4-speed automatic transmission.
