Styling changes for the 1963 model year included a move away from the sculpted sides of the previous years model, to a flatter, more conventional look with an exclusive squared off roofline that included a concave rear window.
Sales of the coupe were down to 21,489 and the convertible was down to 4,401, a drop of 38%, probably due to intense competition from Buick's all-new Riviera, which was in the same price range as the Starfire but had its own unique bodyshell.
 The Pontiac Grand Prix was also restyled for 1963 with a similar squared-off roof, which no doubt stole some sales from Oldsmobile showrooms.
