Black here.

The way the market is right now, the PY cars are slightly less popular than black and CW. So it's the PY cars that get taken apart earlier. If they're not the least popular right now, I think they will be at some point in the near future and, therefore, rarer.

As far as production numbers, there were only about 800 '97 CW produced. They went overboard in '98 with another close to 2000.

However, even assuming that there are close to 3000 CW ITR produced for the USDM, that would still make them rarer in production numbers than both black and PY, assuming that half the production of '00 and '01 was each colour.
