The modern Coke sold in America has fructose sweetener and doesn't taste the same.
Mexican Coke has sugar and tastes like the old Coke.
In my opinion, high fructose corn syrup notwithstanding, Coke still is the best tasting soda, along with Vernor’s ginger ale.
“Mexican Coke has sugar and tastes like the old Coke.”
I can see making a run south of the border for a few cases of that. When reaching the US border again (assuming you survive Mexico), and the friendly ICE agent asks if you have anything to declare...
“Well, just a trunk load of Mexican Coke”
“Step out of the vehicle...NOW!”
