Has anyone bothered to check the accuracy of the speedometer in the new Mustangs, using GPS or some other method?
I know the speedo needle is a little bit hard to read precisely anyway, but I'm just curious if it's reasonably accurate...within 1-2 MPH.
Some cars, even new ones, tend to be way off. BMW tends to make their speedos read higher than actual speed by quite a bit.
