The NUMMI plant was a fair deal. GM knew that to become competitive again in auto manufacturing they would have to become vastly more efficient in assembling cars, and they have. While they used to be the worst of the six major (GM, Ford, Chrysler, Honda, Toyota, and Nissan) in assembly hours per vehicle, they are now the 4th, with the three Japanese companies ahead of them. Although this has created an increase in those in the jobs bank (remnants of the UAW contract), the practices they learned at NUMMI have increased GM's productivity immensely. For Toyota, it was a very forward looking move on their part. They knew that they had to drop the view of American's that they are a Japanese company that produces Japanese cars in Japan. Partnering with GM helped out, as does the fact that they are looking to build their new engine plant in Michigan of all places. GM and the rest would eventually catch up in productivity anyways, so Toyota realized they might as well get some good PR out of it.
