Nobody overpay for "out of production" colors.
I did some web searching, and it looks like B5 Blue will be extended into 2010, with Detonator Yellow available after that, and Plum crazy 4th quarter.
Here's a cut and paste of the press release. I found it on Red Letter Dodge, although I think I've seen it in a couple places:
"B5 Blue will be extended beyond the 2009 model year and will be offered into the fall of this year on 2010 models. Following B5 Blue, Detonator Yellow will be offered on both R/T Classic and SRT8®. If you are looking for your Challenger in either B5 Blue or Detonator Yellow, get your order in today!
The next color to be introduced is one many of you have been waiting for – Plum Crazy, with a tentative production start date in the fourth quarter.
We are still cooking up plans to introduce one more color for the 2010 model year. If we can make it happen, the introduction will be in the Spring of the 2010 calendar year."
