Sorry, but I don't have a clue. Hopefully some one else might be able to answer that question for you.

I believe it is HX09 AAO - depending on how many Vauxhalls there are in the Ford dominated car/van fleet. That is certainly the registration of the one i have seen and photographed. I have a feeling there are a couple!. I understand it is a demonstrator, and has a slightly different livery to the normal West Sussex cars. Jon.
Jon,yes I also think this is HX09 AAO.I also got to photograph it some months ago at Lancing's Open Day(Stn's 40th Anniversary).Its the only one I've seen so far with this type of Batternburg marking.
