I think Larry has expressed the key to the question. If it's absolutely stock to begin with then I think most would keep it that way if they can. If you start out with something that isn't original the cost effectiveness to put it back that way is too overwelming, if possible at all, to consider. So after that decision is made for you, it gives you so much more latitude with the possiblities. I also have one of each and as much as I would love to modernise the original car I think it would be liken to a sin to take artistic license with an otherwise unmolested car. I think circustances dictate the outcome.
