I'm going to go with the S4. The owner of the one I found told me he has Documented maintenance since 25k miles up tile now. All major and minor services are done. He also has 2 sets of wheels, one with snow tires the other with summer performance tires. Plus I am going to use this car for a daily driver for school, to travel from my home in Connecticut to Wyotech in PA will be 7 hours one way. I will travel that at least twice and I want to drive in comfort.
