I test drove a 335i at Bavaria a few weeks ago and after ripping through the anthony henday, the sales guy told me to drive to the back parking lot which is basically an ice field and try to do some donuts and hard stops. I was also concerned about the winter driving with this vehicle but i was so impressed with the stability control after that demonstration I have no concerns about it in the winter. That, by the way, was to coolest part about the test drive
