Simon, there a few contradictory sentiments in your post.
You said "restoring to original condition".
In my opinion the first thing that screams "non-original" is the paint colour, and often from 100 metres away.
At the moment the trend seems to be for survivour or accurately restored cars and the selling time and values seem to reflect this. No science in this conclusion, just observation. Trends do change, however.
Depending on how much of the original car is left, and just how fussy you want to be, an accurate restoration will be more difficult to achieve than something more custom, where you aren't worried about things like using the right bolts, clips, brackets, exactly the right paint, the correct plating finishes etc.
I agree with Byron; if your plan is some form of originality then stick with the original body and colour, do what you want with the mechanicals but make sure it can be reversed if necessary, and do keep all the original bits. In my opinion, done right, Silver Mink is a good looking colour.
At the end of the day it's your car and, after the time, effort and cost involved, you need to be happy with the end result, regardless of the resale value.
