Sorry, most test mules are not produced with new colors. In fact. majority of the time they will be good old white. Another interesting note, the future V8 in the alpha has been in H3s for quite a while and driven on the roads. You may have actually passed one and not knew it. There were many 2007 and some limited number of 2006 vehicles, that had their 5-cylinders taken out, and the body modified to allow for a V8. These vehicles were then driven around the USA. Hoover Dam is a very popular place due to the massive amount of EMI produced by all those generators and the massive electrical wires. Helps prove out the shielding used on the computers. There are actually some vehicles running around with some 2009 surprise components.
What you saw was either a pre-production vehicle where the last two digits of the VIN are EX, or an actual production vehicle. There are actually quite a few actual production vehicles in MI and some have gone on extended trips outside MI to the wild, wild west. These production vehicles are called Captured Test Vehicles, and are part of a Captured Test Fleet.
Eventually the ones with a full production VIN will be sold, usually to employees.
I guess H3builder could let us know how long they have been building them, but I know we have had some production models for a few weeks, and pre-production (EX Vins) for a month. EX are as good as production, but they may not have valideated parts so they can't be sold. Eventually, they are crushed, donated, or kept in some areas for future "things."
The one at the Super Bowl was not an actual production vehicle. It would have been a 07 that was custom built for auto shows, and could never be sold.
By the way, the favorite color in the Captured Test Fleet appears to be the Solar Flare Metallic (the orangy color).
Did the MI plate have an "M" for the middle letter (Example: 001
M020)?
