Price is always dictated by demand v supply. Sandmans are just not demanded as much as say monaros and GTs (present forum community excluded of course).

I can't see a Sandman getting those sort of dollars regardless of the quality of the resto or the dollars spent on NOS parts etc.

I had huge trouble getting more than 30k insurance for our van. It cost a bit more than that to restore and I didn't use a single NOS part.

Build it for the love not the dollars.
