........ and I would like to know ... what the number for the right-hand car is.
Can anyone help?

Now I've looked again at your images, I'm more convinced that the right-hand one is probably a set car.  It lacks quite a bit of detail, like set cars often do.

Back to me being anal about the livery being on the "wrong" body, in 1:1 the four-door was pre-facelift, and the five-door was post-facelift - the front of the cars were totally different, it's very noticeable in the images Kevan posted.
