Yep, that is just it. Most of the "foreign" cars are made in the US. Here in just Indiana, we have a new Honda plant in Greensburg, the Toyota Truck plant in Princeton and SIA (Subaru Isuzu America) in Lafayette. Here in just Greenfield we have Kehin IPT that makes fuel injection systems for Honda and others, and IAF (Indiana Automotive Fasteners) that makes fasteners for all 3 here in Indiana and other. I am sure there are more, but that is all I can think of at the moment.
Most of the "Big 3" seem to come from Mexico or Canada anymore.... I am sure there are still many models mad here, but not like there used to be........
