Coke made in the US is made with corn syrup, but Coke in Mexico is made with real sugar. Are there beverage distributors in the US that carry sugar Coke? How do I find them? Does the cost of importing it make it cost prohibitive?

Depends on how many you plan on importing. Try your local Mexican supermarket or move closer to the border.Or yes, as Lorena said, Mexican restaurants. They tend to buy in bulk so might cut you a deal if you buy a case or something.

Mexican Restaurants always have Mexican Coke and Pepsi. Were do you live?

Local mexican food stores they come in the class container you can't miss them ... They are the best!!!

You have to live deep in the South to find that stuff. That kind of Coke comes in the big glass bottles, so you can easily tell the difference.
