Hmm, bit confusing with the white McLaren. Erik, I don't think it really sounds plausible that CG would use a different F1 to promote the event. The only reason I can think of is that CG had it confirmed as participant for the meeting, but that because it's now for sale, ZAZ museum didn't want to give it out (or maybe the new owner didn't?). Then they could have made a deal with Okamoto to at least have a white F1 present, so that all their promotion material would not be wrong.
Now, to keep in line with the regular sharing of beauties, I have come across another beauty. We know this car, but we only had a very very low res picture of it. This one is unfortunately not too sharp, but it's of a more acceptabe size
