The sheer ingenuity of the thing is mind boggling to me. As an engineer, I am intrigued by the person or person's that were able to put this thing together. If I thought I could keep it running, I would move it to my ranch, but I am sure that neither I nor my associates could keep it in repair. But, it is cool.
One-hundred mph in that machine would be way too fast for me. If I was purchasing, I would take his word for the top speed. To me, it's appeal would be to tool around our small town and piddle with it on the ranch.
