2.0 litre and 3.7 litre engines are manufactured in USA - all the COO (Country of Origin) labels I've seen (on those engines) are marked USA.
The first few cars built for the USA market had their engines / gearboxes fitted for the assembly process, then subsequently removed. Now they are assembled without fitting, but as far as I can see MMC ship the engine/gearbox along with the car for dealer fitting. "Replica" rules?
