Mark,
I know of what you speak! As you know, that delimma isn't any easier in the sunny South. Today would be a perfect day to drive and look at Fall colors, but I'm painting several small parts.
Three thoughts:
If you are ever going to truly restore your car to original, it's not going to get any cheaper in the future. (If anything, original is rapidly getting more expensive and harder to find.)
But if you are happy with a local show driver, fine! Most of the guys I've known who restored to a true show car did a whole lot of work, spent a large amount of money, and agonized over never really getting to drive it!
If you truly want to restore a car and have a driver, then you need three cars: the show car, the driver and a parts car...
