Just FYI-
According to the Dodge & Plymouth Muscle Car Red Book by Peter C. Sessler;
1970 Chally total production was 76,935 total units
1970 Cuda/barracudas was 50,617 units
1971 Chally was 26,299 units
1971 Cuda/barracudas 16,159
1972 Challys 22,919
1972 Cuda/barracudas 16,142
1973 Challys 27,930
1973 Cudas/barracudas 19,281
1974 Challys 11,354
1974 Cuda/barracudas 11,734
According to Galen's books;
1970 Chally total production was 83,032 total units
1970 Cuda/barracudas was 55,499 units
1971 Chally was 27,718 units
1971 Cuda/barracudas 18,690 units
1972 Challys 26,633 units
1972 Cuda/barracudas 18,450 units
1973 Challys 32,596
1973 Cudas/barracudas 22,213
1974 Challys 16,437
1974 Cuda/barracudas 11,734
so it depends on which numbers you want to believe-
but one thing is for sure-there are a helluva lot more challengers out there-
so that is probably the reason for the price variance between the different years and price.
