You can see Koenigsegg at UK only if there're some people has a Koenigsegg driving on the road. It's because the Koenigsegg cars are not made in UK, Koenigsegg CCX, CCXR, Agera, Agera R... All these Koenigseggs are made in Germany instead of UK. You can go into a factory tutoriol with Koenigsegg cars. So if you live in UK or live in UK and want to see a Koenigsegg car, there'll be less chance to see a Koenigsegg then in Germany. But you can still see some Aston Martins in New England.
