The plates are just show plates, there is no way they can be real. They are english plates (white on the front yellow on the back, both reflective) and there is no way you can make the word "Kenwood" from English plates and register it.....
Second why have fake English plates on the car if its being displayed in Holland?
and I would assume the pics were taken a while ago, since the car has been out for something like 10 years why would Kenwood still boast about supplying the Stereo? technology has moved on since they made the sound system for the Mclaren so I dont think they would still use it as a promotional tool... but I could be wrong
Judging but the second one, I think the pics are scanned, you can see a wedge of light at the bottom, like they haven't been careful placing the photo in the scanner and its got tilted.
Here is the Webshots album I got them from, there is a couple of other photos I have never seen before in there too....

Okay thats everything I know or can logically assume about the car
