Over 30 years ago Toyota implemented a program called total quality management (google TQM, many books written on it). Basically this is a program that has become the benchmark for product quality in manufacturing. This program was actually invented by an American (I forget his name) and tried to pitch it to car companies in the US, but they were not interested. He took this program to Japan and Toyota jumped all over it. Presently, so many of the parts are subcontracted to other firms that TQM is not as valad as it once was. I have many friends that work in a Toyota plant in Indiana that have said their cost cutting in recent years have significantly sacrificed quality. As for domestic producers I am sure the big 3 picked up on the TQM model in recent years. This is taught in business school programs as the standard for quality control, so newer executives would be on board with it.
I have 3 Dodges, a 2005 Durango with 75K on it that has had only regular maintenance and 1 set of tires. Other than that it has never seen the shop. I just recently sold my 1997 Dodge minivan with 230k and it served me well. I just bought a new Dodge Dakota and it appears to be well made so far. I have had many GMs as well with very good results. At this point, buy domestic or foreign, as far as quality goes I don't think it matters. I am however a very proud American, so that's where I spend my $$$. For now, while we are still in a free country everyone can buy whatever makes them happy.
