Was worried for awhile that I may have overpaid for my e92, but after reading through the thread, I feel much better about it.
When purchased: August 2019
Year and Model: 2009 E92 M3
Color: Space Grey (carbon roof, black leather, carbon interior)
Miles: 70k
Options: EDC, iDrive, Comfort Access, (still unsure what audio)
Trans: DCT
Paid 22.5k
The only thing that almost held me back was that the car was re sprayed. Per the previous owner, it was hit up with salt from a salt truck, so the insurance covered a full re spray. Owner was up front about it and the paint looked great, so I pulled the trigger.
