All A2 Jettas were Made in Germany until 1990 (for the NA market)
All A2 Golfs were made in either Brazil or Mexico (for the NA Market)
That's a MAJOR difference.
No Dave. A2s were initially manufactured in the Westmoreland Pennsylvania plant until maybe 89 or so. I dont know exactly when they moved production to Mexico. They definitely made golfs and GTIs there and I think Jettas too. Certain trim levels of Jettas were exclusively German. (I know GLIs in 87 were German.) Lots of A2s running the "Volkswagen of America" door sticker though.
I am not aware of any A2s coming from Brazil, at least during the 80s. I think the only Brazilian car imported to the US in the 80s was the Fox.
