You are not ignorant at all, forgive my imposition that made you think that you might be...
A number of brands in the UK, are Chinese models rebadged. The UK market is big enough to have a models with a name all their own. For example, the Maverick line of models are only available in the UK under that name, in other countries, they are differently branded, and sometimes with minor specification alterations. This is because the Chinese manufacturers give their big customers the option to have their own branding, different bodies, box-art, all that kind of thing, but the underlying cars are always the same.
You will have no problem getting any of the Nutech cars or parts in Europe, if not direct from the UK, don't worry.
