Oh, I agree with you. However, in my case, the dealer edition is significantly more expensive than the non-dealer version just because of color. The Ultraviolet and Lava Orange colors are in the thousands now (with a $2000 Lava orange one on ebay now), the white and birch green ones (dealer editions) are about $500-600, whereas the non-dealer silver one is about $300ish at least according to ebay. If GT Spirit made one, it would be even less than that.
I got a birch green one (#217/911) for a lot less than it should have been. Then again I bought it on ebay about 3 weeks ago and it's not arrived yet. Perhaps it was a scam!
