CAR-IDENTIFICATION LATE SPRITE & MIDGET (1967-1979)

A model year does not necessarily coincide with the year in which the car was built. For example, it may be seen from the following chart that while a car built in January 1972 is indeed a 1972 model year car, another one built in August of that year is a 1973 model year car. There are several different reasons for this. One reason is that it is easier to bring in changes in a model's specification when production has been halted already for a holiday shut down. Another reason is that motor shows usually took place in the Autumn and Winter, displaying the following year's new or updated models. Detailed here are the Sprite and Midget model years relevant to our categories.
