Definitely Germany.Not sure if the new Corsa is still going to be built there or if its ear marked for somewhere else.The Mokka will be built in Spain shortly which should cut waiting times down as its currently made in Korea.
Ahhh, my baby was born there. **Wipes tear from eye**
On a more serious note, that plant is a serious piece of kit. Knocks the socks off the old Luton plant. I had a tour when I did work experience with Vauxhall Aftersales back when the plant was gearing up for Vectra C. It was impressive but not as cool as Eisenach looks!
