Haven't kept up with this build in a while, but I got to say I am impressed with how it is turning out! I agree with your wife on reviewing your priorities on what your expectations are. You probably would have spent upwards of $15,000 for all of the work that you and your buds did on her, and that speaks volumes for its quality. It's no different then other parts of your build, where your expectations changed, and all of a sudden something you were more than happy with in the past becomes unacceptable today. You are simply resetting your standards higher as your abilities to do things gets better. More likely, as perfectionists go, you are not wanting people to notice flaws in work you have done. All thoughts of these "imperfections" will vanish the second time you take the car to a show :), and many, like myself are more impressed with someone who has done all the work themselves.
So finish her up and get out and put some miles under that rubber!
