I liked amex and I got the green charge card when I turned 18 in college and have been a cardmember since. I think the AF was only $50 back then, for $95 I might not have done it. I actually think the green card looks the best and it's iconic. I've upgraded since but when I see a green card now (which is very rare) I definitely feel the nostalgia.
I read somewhere that Warren Buffet carries a green card. I figured, that's the ultimate statement in status. No need to carry a fancy Centurion or whatever, you know damn well whatever amount he charges on his green card will go through, and he really doesn't need any of the Centurion perks... he travels on his own jets, for example.
