Bill,
Although I have not driven on the highways at anything approcaching the speeds listed in this post, ( My car won't even go that fast), I do disagree with you on the speedometers not being accurate. I have had mine tested by the CHP with their radar at 50,60,70,80,90, and 100 MPH. It and the tach were exactly on with the readouts in the test equipment. However, not being to much into authenticity for the car I use a VDO electronic set of gauges and the speedometer has a computer chip that is programmed to match. Really works great when changing tire sizes or gears. All I have to do it push a button, start the car, drive a mile and the computer chip will calibrate the speedometer for the new gears or tire size.
