I have purchase a number of cars in my lifetime and I have never ever looked at the speedometer. I will be looking now. Not for the reasons mentioned in the article but how easy it is to read. Mine sucks.
Also I have a tach. No idea why since it is an automatic. My guess same stupid reason as the speedo going to 150MPH.
