Licence plate changes occur in Britain on either March 1st '0x prefix or September first '5x prefix. As you can plainly see this car was registered on the road before September 1st. Way before the Frankfurt show appearance
If need be I can call home with the VIN to see exactly when it was put on the road, but as all postcode licence plates beginning with a Y are Yorkshire region, the likelihood that this car was registered at Thorne (BMW Distribution UK) is an almost certainty - it was no doubt on the road June/July of 2007!!
