Plastic 5K wheel flares, do they exist?

[illuminaudi at comcast.net]

I was looking through Bentley, and in the painting procedures section (don't know the # offhand) there is a list of parts made out of different types of plastics, and how each type should be painted, prepped etc.  In one of the lists, there is an item "wheel flares."  I've never seen these on any cars, but I would guess that they aren't Euro-only since this Bentley is a US/Canada only edition.  Is there a part number for these?  I don't have a Family Album or parts list to look at.  
I've been looking for plastic fender flares similar to those on later BMW 6ers, and these sound like they might be just that.  Ideally I'd like a look similar to the Sport package fenders available in Europe.  I don't really want to do the 20v or V8 fender-bumper swap either, too much money and too much of a 'pose' for me.

TIA

Matt
