Mine is 1535 as per scale weight with just under half tank fuel and no driver. The general dry weights from bimmerpost etc are around 1650kg dry weight I think
@ Kish, disc weight is fine, I'm sure it will be close enough. What's the weight on your car?
Scales may differ depending on calibration, @922-ZN that sounds quite light for an E92 M3 unless you have removed seats, battery etc. best to compare with another M3 on the same scale, same fuel etc.
