I have heard of only one or possibly two in my extensive time of MTorque/M3Torque and CSLRegister. How many are left now is anyones guess but I cannot imagine many were specified without these options. The one that sticks in my mind also had the 'normal' halogen lights ie no xenons.
i owned one without air con and it was a nightmare in summer. As there is not much between you and the engine it can get a little hot in the cab. If I was to buy another CSL I would get one with Air con.Agreed , no radio, no air con in my old one and not good in summer.
