Here is their response to my email sent a couple days ago:

I'm sorry, we haven't done a Viper yet. It's in the pipeline, but we're not to that prototype yet. Once that car is done, it would be up to the owner as to whether or not he would let strangers drive it. We will have full dyno results once it is done and of course lots of pics. I'm sure the owner would take you for a ride and let you look all you want. We'll have to wait until that time comes though.
We are finishing up the mustangs right now, then we have a C5 scheduled. Once those are done the Vipers are next. We only work on one type of prototype at a time. This way we aren't running back and fourth from say a C5 prototype to a Viper prototype. It allows us to give total focus to each prototype.
Let me know if you have any other questions.

Seem like really nice people, however, no car done yet is a far cry from being able to sell a kit.
