L820 KPU isn't numbered 000 and has a normal cosworth badge in the banana pod, it doesn't have a Monte steering wheel, chrome hand brake button and I'm not even 110% sure its even Jewel Violet as it looks more like magenta, unless the only pics I have seen have been darker?
I had always been led to believe no. 000 was numbered 000 as so many people has seen it at a show next to the other prototype yellow Esc Cos which was RWD with a N/A V6 cos engine. Whether its the same car or not I don't know as despite searching for the yellow RWD and no.000 pics that Ford bought out for a RS show once I still can't find out any more info.
Personally I think L820 KPU had a multi purpose for Ford as what you can't see is it has a mk5a front end! yes a smilie face grill in the bonnet! and the oval side winkers. So I think it was a concept/prototype for the commemorative/Monte models/Small turbo/mk5a
