VW also has the following vehicles as a manufacturing aspect Bentley, Bugatti and Ducati Motorcycles. It also manufactures commercial vehicles in Germany. It also has 19% share in Suzuki Motors. If my memory is right VWs are manufactured in 153 countries.
Regarding the old beetle being built in Mexico, I have family that lives in Texas and they claim that VW is still manufactured in Mexico.
VW is definitely manufacturing in Mexico - over 16,000 employees.
Just not the old beetle.
