My wife and I are looking at a 1995 540i. It's going to be my wife's car, and she has never owned a rear wheel drive car before. My concern is her driving it in the snow. I tried to teach her car control in the snow in my car last winter, but she was too scared to try. The 540i we looked at does have traction control...but how effective is it in the snow? Does anyone have any experience driving one in the snow? Thanks for any feedback!
