According to the WSJ (http://online.wsj.com/article/SB125046466790535335.html), Fiat will bring assembly of it's b-car 500 (aka Cinquecento) to the Toluca, Mexico plant where PT Cruiser is built.
This looks bad for Obama, and there is going to be a lot of heat. A lot of people are going to reasonably ask, "why are we spending government money to prop up assembly jobs in Mexico?". I expect Congress will have hearings, where members who have plant closings will throw shoes at the Italians.
"When a difficult decision has to be made on matters like where to open a new plant or what type of new car to make, the new Chrysler, not the United States government, will make that decision," said an administration official. "It's quite consistent with the plan from the start."
