Exploder, I hope that Dutch site is right - Cadillac doesn't really need to make money on these, it needs a halo, even if it costs them some money and us some more expensive CTS-Vs
BTW - Here's a list of systems that are typically tested for type approval:

Here's the process this third party makes you go through. I'm not sure if GM works with someone like this or if they have their own export group (I'm guessing they do). Either way it sounds like the sort of thing that could keep a few people busy for a couple of months if they have to retest the engine, the brakes, the tires, frontal impact and pedestrian protection stuff. The front end is different, the weight is different - it may not be different enough to matter, but the EU isn't going to sign based on "it's close".
