if classic amex = silver amex = gold amex = no limit
how come those 3 card has diff annual fee o_O....blur~
Here's what I know. The difference between green, gold and platinum is simply the amount of services you get. Green is the basic card, gold gives you access to certain events and services and platinum has their concierge services, Starwoods Gold Preferred membership, etc. If you travel a lot for example, Amex Platinum gives you free access to some airline lounges, free room upgrades when you stay at a Starwoods hotel and other stuff. Travel 2-3 times in a year and this can be very addictive
There is no pre-set credit limit, but they do look at your spending patterns. Put a big purchase on the card that's beyond your usual purchase and they'll happily call you and ask what the hell is going on, sometimes saying that you need to have cash in your bank account before they'll let it go. I've never had this but then again I don't put big RM20k purchases on my card.
On the whole though, I think Amex is riding very much on its brand name only. Many Platinum Visa/MC have features like the above already and Visa Infinite is competing with the Centurion (black) card already. It's really up to you whether or not you want/need an Amex card as a status symbol

Anyway, just my opinion on it. This applies only to the charge card btw, the credit card I think is different.
