You know, I've always heard that one is rare and the secondary prices seem to bear that out. But everytime someone mentions it on the HWC board, it seems that quite a few people post how they found X amount of them at Walgreens on Black Friday, etc., etc. I know anything less than 10K is rare for a mainline HW, but I just don't know that I believe it is as rare as reported.
I've read those stories as well. The majority were found at Walgreens but a few others were found in other locations.
The designers wanted the color change because the red wasn't what they wanted.
Mattel stopped saying how many T-Hunts are made each year some time ago.
That being said, with the small amount made anyway and the gray showing up at the end of the run, I am sure that there isn't a huge number out there.
