Is anyone else having an issue with speedometer acuracy?

That's unfortunately not unusual for BMW. My Z4 is much more accurate than my Z3 was, but is still about 3-4% low. Given that my Z3 was about 8-9%, I'm pleasantly surprised with only 3-4% for a BMW.
I tend to rely on either my new Escort Passport 9500ix with display set to mph, or my GPS if it's turned on.
