A total of 134,867 Mustangs were sold in 1973. Total production was up 7% year on year, the first year of growth since 1966. This was the final year of the first generation Mustang and it seems that the company was offering incentives to move the final models. The Mustang needed to make changes and plans for the Mustang II were firmly in play as the ’73 was being rolled out.
Note: We had trouble getting more details production splits which is why the high level numbers and the detailed numbers below are basically the same for this model year.
