I was leaning toward the base TL with Navi, but after test-driving both the base TL and the S it was all over. I drove the S first and the base TL really lacked the torque off the line. This is a great commuter car, comfortable yet sporty. I have the Crystal White Pearl with the Ebony/Silver Interior. I get compliments on the exterior color with its iridescence. I have about 900 miles on it now and the trip computer is telling me that for the past 650 miles (reset this after the initial tank of gas from the dealer) my MPG are 26! My commute is mixed city/highway (Philadelphia to NW Suburbs, 27 miles one-way).
Traffic monitor saves me time going home. Engine growls when you want it to. Cabin is a vault with windows up, I barely hear vehicles along side the car.
Fold down rear seats. Cooled from seats. Blind spot monitoring system.
