I love blue. I just sold a blue car. Blue looks great on the 3, in particular. I thought red was the right color for the S, and blue for the 3. But my dad has a blue S. Both my wife and I really liked blue but since it's the most common color, I was sort of leaning towards red for some reason.. even though I thought it looked better on the proportions of the S than the 3.
Pulled the trigger and couldn't be happier. The car looks REALLY good in red, I love it. Don't love the aero wheels, gonna put the cap kit on soon. Will tint the windows and probably get rid of the chrome around the windows somehow. Chrome door handles are okay though.
