Funny, My car is L529677 also a LOS 04C build, Very close to the one for sale. <529407>
For comp,,,,, My tag = M044 His = J480
The Chassis Broadcast Copy (Mine) does in fact Have Z11,,,,,,"5Z11AA", "5Z87KM", "5Z720BA" typed in below all the data blocks.
Very quickly someone will become upsidedown on this car.
