The build sounds great and I too look forward to hearing her run. I think your wife wanting to be part of the car and drive as well is great. Of course I do not know her or her likes and limits but what a chance to make her part of the car. Would she like to take a drivers course at Bondurant's
Bondurant Racing School ? Maybe a great way too spend some time together and let her sneak up on the thrill and power of what this monster will have.
My wife loves the cars and events but will not drive, it's just hard to bench race with a passenger. I think part is not wanting to crash my baby but she also is a bit afraid of the car. Even with my insisting she does not have to drive fast or push the pedal any harder than she is comfortable with but is a happy passenger. I guess I am lucky not to fight over who gets to drive on the other hand.
Keep us posted on how things go and when we will get to see your Toy.
