well I used to run a car import business and the only difference is that depending on the country some items of kit (winter pack in sweden) are std.
The easiest way for a non expert is too look in the service book and look at the supplying dealer pdi stamp, this will be either a Uk dealer or a UK town or foreign town. All the manuals that came with the cars I supplied were official uk manuals so the only spot is the stamp.
Other give aways are:
won't be on UK VAG dealer system - but only a dealer can easily check
simples is to put the reg no in euro car parts on line system if the car details don't come up then often an import
and finally, yes I do believe that one of the vin numbers is the supplying country but not sure which one.
also provided it has been specced properly (main thing to check is alarm as this will invalidate your insurance and you can spec without UK alarm in some euro markets) then it is exactly the same as a UK supplied car!
