Too bad they don't offer a Manual, like on the 3.0 CSL (apparently made to work with the extra power/torque in that model)...

This is why I find the M2 more attractive than the M3 CSL - manual transmission in the States.  I must agree with Christian that the M3 CSL looks much better at the rear than the M4, which, for some reason, appears too feminine for my tastes.  This being written, whilst the M5 CS is an amazing automobile, it appears much too ordinary on the street.  The Audi RS7, for example exudes power, with the M5 CS looking too much like the average 5-series.
