I have a GMC with a sticker in the door well with a picture of the great state of Texas, that says "Built in Texas by Texans". While that sold me on the vehicle as soon as I saw it, obviously it means little to you since you've admitted you wouldn't care if the sticker was a map of China that said "Build in China by Slaves" so long as you liked the product and thought you got a good deal on it. There's really nothing else to say, is there.
LOL
Your GMC parts were made in Mexico and China...
That sticker doesn't mean anything other than it was assembled in Texas...
Wow, you believe in stickers... It should say Assembled in Texas, My father worked at GM for thirty years and his #1 complaint was not people buying foreign cars it was the fact most the part fabrication was done in Brazil / china / other.
