Although I couldn't afford to goto the press day on Tuesday 22nd July, I have found a photo gallery and video of the press day on the AutoBild website.
The Vauxhall Insignia, Nissan Qashqai+2, Honda OSM, Alfa Romeo MiTo and many more, had their world debut in London. Since I am going tomorrow, I will take as many pictures as possible.
