So, first it is not a complete kit. You do not have the cable and the USB port for the glove box. You also do not have an emulator or instructions on virginizing the HU and reprogramming it to the VIN.
Second, you have the parts from 8 M3 cars?
You seriously might want to reconsider your selling strategy and pricing. Cause over on the other boards we just showed another person where $500 will get you a complete setup WITH emulator.
