My Corolla was built in Fremont, CA by UAW workers at the combined GM/Toyota plant. Many parts are U.S.A. sourced.

Almost all Corollas come from Fremont, and the serial numbers start with 1N.

I buy American too, and picked Corolla for that reason. Used to buy Saturns but the new Astra is made in Belgium by a GM subsidiary. How American is that?
