1983 - 1993
For model year 1983, the emblem at the rear of all 240 models was changed. No longer did it say 242, 244 or 245. The badge just said 240, as part of a new designation strategy. In reality, however, msot people continued to refer to their cars as a 244 or 245.
This change did not mean any large-scale modification to the cars.
For more information, please see the relevant models; 242, 244 or 245.
