The Key thing to always remember and one thing I do get concerned about when I read these comments from "enthusiasts" is that these are people who know exactly what they are doing in terms of goals for the car.
It is surprising how little credit the people responsible actually get from some "enthusiasts".
Each car from BMW whether a series model or indeed an M. is a combination of team work that involves many departments from initial conception, design , engineering , marketing and assembly. And through this process ideas are evaluated, tested , approved and discarded until that right solution is evident. Even the assistants that pour the coffee and file the minutes are part of that process.
