Hey, if YOU like the 71-74 B body styling more than any other model, good for YOU. I won't try to convince you that you're wrong, I just don't agree.
When I look at cars and the different models/styles/designs, I do try to understand why some models sold so many more units than others.
The '70 Chevelle, 69 Camaro, 64-66 Mustangs used to dominate the street machine shows in the 80s around here but those body styles never appealed to me like a 68-70 Charger.
I stand with bewilderment that people bought more Chevelles than Chargers. I simply see that as a man choosing an average looking, short overweight woman over a taller, prettier, curvy one.
I absolutely understand that the 64 Mustang far outsold the 64 Barracuda because the Barracuda was hideous in comparison.
When people refer to the "Coke bottle styling" that means the accentuated curves immediately visible in the 68-70 Charger. If there is any "Coke Bottle" styling to the 71-74 B bodies, it a 2 liter bottle of Coke.
If you like that, good for you. 1973 was the best year for sales so you may have a better chance to find one at a better price than we have finding a restorable 68-70.
