As pointed out, there are actually a lot more '70-'71 cars then there are '72-74's. In fact if you look at the Challenger production #'s
1970=76,935
1971=26,299
1972=22,919
1973=27,930
1974=11,354
you find out that there are actually more '70 challengers than '72-74 challengers combined, with total production for all 3 years at 60,572. So there should be more '70-'71 owners on here, just on statistics.
As far as the Challengers go, I like the '70 and '71 grilles better, '71 is actually my favorite. But like a lot of folks I actually like the '72 to '74 tail lights better. And for the cuda's I think the '72-'74 models look the best, love the round tail lights! The '71 grille is my favorite again, but only by a little. And I actually
don't like the '70 cuda grille.
I agree with most folks in that the '72-'74 cars get a bad rap due to the lack of the big block and special models (R/T, T/A, AAR). But the collectors have gone nuts over the earlier cars, and a lot of those hi-perf models are just unattainable ($100k plus) for regular middle class folk.
I like my '72, and although I may change it over to a '71 front end, it'll still be cheaper to do that than it would be for me to buy a '71 in the same condition. And sadly enough, I have had my Challenger mistaken for a Camaro!
