With Ford GT production officially ended there is now an accurate assessment of how the GT's colors and options break down over its two-year run. You can see a larger (clearer) version of this chart at The Ford GT Forum and, if you're a fan of these cars, this kind of information is fascinating (if you're not, you likely put us GT freaks in the same category as people who wear Vulcan ears or have a "Mint on Card" version of every Star Wars figure -- not that I belong to either of those groups, dammit!). A few interesting points that are obvious after looking at this chart:
1. The bulk of GTs have the "upgraded" McIntosh audio system (too bad...)
2...
3. If you have a yellow, strip delete car with standard wheels, standard audio and black brake calipers, you have one rare GT!

Whatever happened with that issue with the GT's frame cracking ? Was that just a rumor?

The frame never cracked, just the suspension pieces because of a flaw in the production process. Ford replaced all the units that had the bad pieces with billet aluminum units (very sweet looking -- and expensive, but the cost wasn't passed on to owners). Mine has the billet A-arms and they just add to "wow" factor when you pop the engine cover. Ford ultimately fixed the process for the late 2005s and all 2006s, so those models have traditional (non-billet) aluminum A-arms.
