SL550 v.s. M6
if only most M6 drivers can drive it to its potential. power button on,gear changes to highest and fastest, edc on, DSC off. and of course being in the power range when racing, high rpms. launch control aswell is effective when used wisely. all of these things is what most M5/M6 drivers arent up to snuff on, esp a women driver (sorry to say)
