I would go along with the some of the comments made on here. The CSL is a 'special' vehicle but to the outsider and unconverted it will probably be FBMWSH along with a BMW warranty that they seek (along with low mileage
) as their ideal car. That said these cars are getting older and the low mileage and hence warrantied vehicles will be in short(er) supply so they will have to turn to the specialist independant serviced vehicles.
At the end of the day most will be worried rightly or wrongly about the clutchless manual side of things as it is still relatively new to most ie how many old high mileage vehilces are out there (6+).
The real enthusiasts will at the end of the day look at its condition and those that have clearly stinted on the car will be struck off.
Just my personal opinion of course.
