If the 5th Gen was built in Mexico:

1) there would be different suppliers or factories (with less overly oppressive environmental restrictions) for the parts
2) the windshield would hopefully come from someplace that knew how to make windshields instead of the current suppler/factory and would hopefully be much less fragile
3) the paint would come from another suppler, additional colors would be offered, like the Highlander has, and it wouldn’t fall off in the wind or get scratched by sneezing on it. Hope fully it would be much better than the interior latex like crap they are using now.
4) delivery fee would be reduced
5) time between order and delivery would be reduced
