It would be nearly impossible to purchase and restore a Sandman for under $20k Start adding a few GTS bits to any reto and the prices start to climb very quickly. Wheels and tyres alone would be hard to purchase and restore for under $1300.

Once you start the costs just keep accumulating. Unless you can do all the work yourself and thats a bit tricky when you talk about re-chroming ($350 for a bumper), re-upholstering ($700 for 2 seats) etc.

Its a good buy at $25 except for the windows. That can be fixed for about $5000 if you pay to get it done. More fun in doing it yourself though. I have only seen about 5 fully restored examples for sale in the past 3 years. None for under $25,000
