Hi,
I am in the exactly the same situation. I decided to do the restoration because there really isn't a truly rust free body to be found. There are some out there that are less rusty or less molested than yours but the body is the expensive part if you have a solid one it would cost less than 20-30k to scare up an engine top interior and chrome.
I know the man doing the restoration and I trust him and I know that he will return it back in pristine shape. I alsoo resisted the strong urge to do it halfway and save money.
For comparison my car was previously molested by a butcher who replaced the fenders and quarterpanels and brazed them on. My friend Rick is taking it back apart replacing the rocker assy's, inner front wheelhouses, upper braces, cowl sides, rear inner wheel wells etc. Should end up around 15k with parts.
