What model do you have and what is the first character of the VIN?
As mentioned above the majority of toyotas sold in the US are made here, 70% actually.
Every Chevy, Ford or Dodge I've owned since 1985 had "Made in Mexico" all over it.
The '79 and '84 toyotas both had stickers on the bed behind the cab that read " Made in Long Beach, Ca., U.S.A.
The last time that I looked, the little Yaris was made in Japan, unlike some of the other Toyota models.
