Milt, I'd think it all depends on what kind of toy the buyer was looking for. Yeah, I have the car some would call an "unmolested S"...tho she has fooled around a little bit.
Now it's almost an obligation to keep her maintained & nice. Should my lottery numbers ever come in? I'd go for a street 911 hotrod, not necessarily a track only car, but "close to the edge"..still street, but with track goodies. But that's just MY desire. Your theoretical T done to RS clone specs? That describes Tom Wilkinson's car to (excuse the pun) a T! Only his is sans flares or ducktail or stripes. I drool every time I see it. If I had the bucks,I'd pay damned good money for one similar. But Tom's may be the exception...because on his car, with his attention to detail, it has been done the right way...no cut corners, everything absolutely top quality, labor and parts.
Here's a pic...
Here's his engine...
Yowzer! I'll admit it...this car turns my crank...big time!
