I had secretly hoped that you might change the "showroom" model for a real one!!! i beleive this particular LE500 belongs to the chap that runs the MGF Register in the MG Car Club. the one next to it is also Crystal White.
Its a pity that we still have many gaps in the list of colours, dont know how we can get more members to post.
I have a photo that i took last Sunday of a 1999 MGF in BRG and a 2009 TF135 in Racing Green standing side by side, thin it would be worth sending for the Racing Green??
I've knocked up a quick gallery over here
