I kinda think this is true as well. The first publically owned GT was auctioned off at Pebble Beach before the car was even built. Winner got a trip to Wixom to see the first car off the line. The retired Microsoft exec, Jon Shirley paid around $557.5K (net) for an $165K MSRP car which got all the dealers thinking there was a lot of money to be made when and if they got an 05 GT allocation. Thus the sky high prices for the early 05's off the line. The first publically owned GT (chassis S/N 10) was midnight blue with white stripes, McIntosh, BBS wheels and grey painted calipers.
Believe there is only one "sonic" blue GT which was a "one-off" factory produced GT Ford did for the American Cancer Society aution to help them raise money for the cause. It was auctioned off 10 Sept 2005 and went for big money as well and now appears to have resurfaced for sale.
