Check this out !
There's this 'easter egg' thing that shows you information about your Z/M coupe....and you do it like this:
With the engine off, press and hold the trip reset button, then turn the ignition key slightly until you see something saying "test------...". Now release the button, and press it briefly several times.
Each time you press it , a specific data appears, and , when I did this, one of these numbers shows the word miles. The reading was 7504.
Now this upsets me a lot , because I just bought this car from a dealer, and I have only 2028 miles on it !!!!
Can somebody try this too , because I am not sure if this is the second (backup) odometer reading or the number of miles left until service is due.
