the E63S is using PZero and the M3 is using PS 4s? is it 4S* or 4S? personally I always love and have better experience with PS more than P0 regardless of car and generation.
drop dead gorgeous, more alluring, more beckoning than everything and only less exuberant and intriguing than MBF. between the two above I vote FB2. but I thing FB 2RES recto is more sexy yet aristocratic while the verso is more spectacular.
