No offense. Given the product produced (especially the 1M, the first-ever so called M product that use a non-M engine and parts bin assembly) during Dr. Segler's M Dept. tenure, personally I consider Mr. Segler to be more suitable to run the MINI brand other than the more performance/technical oriented M brand. I totally support BMW's decision to put a person with technical background to run the M brand.
Look at Ford, before and after assigning a technical guy as CEO, big change, big improvement!
