One of the issues with all of these 911s is the increasing value.
Values for unrestored, clean pre-1973 cars have gone Ferrari-crazy; and the values for solid non-numbers-matching but well-restored cars have also skyrocketed. For me, it would not have made sense to have a $5K paint job done; to get the most bang-for-my buck I would have to have done a $20K body resto, which would have likely added more than that to the current value and even more to the future if trends continue (note that I had VERY little rust for an early car, but it's always there somewhere in the pre-galvanized machines). That was a big factor in my decision to pass it along to the next caretaker.
Although SCs haven't hit this point yet, it is conceivable that they could become "investment grade" in the next few years, in which case you may be kicking yourself about taking the economical way out on any repair/resto. Just a thought.
