In my new car options I am considering the New 2009 Toyota Corolla S. I am getting the Sport Package with it and will also ad the Moon roof. But I have 3 options with this and I am considering 2. They are basically the same price. The 2 are similar in everything except that one come with JBL Premium sound system including 6 in dash cd changer, 6 speaker and more. And the other one come with Vehicle Stability Control VSC and Traction Control. I am more inclined for the latest as is suppose to make the car safer. But I had never try it so I will like to heard some recommendations on with one will be better the premium sound or the VSC. Does it really works? Does it make a difference? Please help me choose.
