Or the project was shelved and they then decided to sell the carbon body panels slated for the CSL to M2 and M2C owners to recoup R&D costs. When have they ever offered such elaborate Mperf parts for a M model? Personally believe those parts most certainly were for a different program and plans changed. If and when a M2 CSL does come, test mules will be seen first(6+ months before any announcement). The M4 CS was seen testing on Nürburgring well over 6 months before it was even announced. Then wait for start of production and delivery. You are at least a year away from when you first see a test mule.
