The first 50 seconds of this shootout pretty much sums up this thread!!
But seriously, I don't get what all the fuss is about... If you're happy with your M car enjoy it! Same for the M-sport crowd.
Do you really think 90% of the daily driving we do, stop light to stop light or highway cruising, is going to make that much of a difference??
Yes, running a heated lap around the track will definitely expose ///M vs Msport, but if we're both driving to get groceries or just to get to work dealing with bumper to bumper traffic, it all becomes negligible... Granted I love the M4 and visceral feel when I can open it up, but living in Ohio\Michigan, I rarely get the opportunity between idiot drivers, traffic cameras, and stealthy cops!! Now if I was living near the Black Forest!
