Let me just point something out here.
The last Ford GT was revealed at NAIAS in January 2002. John Shirley's car got delivered in August 2004. It was 946 days between debut and delivery.
The current Ford GT was revealed at NAIAS in January 2015. I've got 2 of them sitting 10 feet from me that were delivered by March 2017. The first one showed up 765 days after reveal. We still have about 5 months to go until we reach the same point at which the first 2005 GT was delivered and people are bitching that the pace of the program is slow! I'm not surprised some people don't know this, plus the internet wasn't nearly the thing it is now so each day is an eternity, but you'd think if you fashion yourself a GT historian you'd be aware of this information.
The 05/06 car wound up at 9 units per day, but it took a long time to ramp up. They were building 2-3 units a day for a significant period of time. The max on the new car is 1 unit per work day. It's not a surprise it's taking them a while to get there, especially because the car is vastly more complicated and labor intensive. They constantly learn/change things throughout production on a low volume car like this. It's like the difference between an early 05 with the clamshell clips and a later one without it.
Delivery and production are not the same thing. There have been a lot more than 5 cars built. As they batch them geographically or they get software updates, they have cars complete and waiting to go out right now. Just for kicks, my VIN is 0040, and my car is supposed to start production this week. Hopefully it does, but I'm not sweating it if it doesn't.
As for media reviews, media drive is this month. That's not a surprise to the publications. If they wanted to publish something about getting to go out early shotgun, and Ford granted them that opportunity, that's their choice. I would surmise they would rather have something to publish shotgun before others rather than publish drives at the same time as everyone else.
