The points you raised are all really personal choice, but since you asked for opinions:
Wih the stop and go in Atlanta, I think I would go with the Auto.
I have owned both white and black cars before, and never again. They truly look wonderful when they are clean, but they never stay clean for very long!!! I have SSB, and it is great, but I really like blue.....
I think the current offereing has plenty of power. I don't understand why a second off the 0 to 60 is so important for a car that spends 99% of its time cruising down main street at 40 mph, or on the interstate at 70 mph, + or - 30 mph!! I have had mine to 130, and had more to go. That is good enough for me.
And except for stormbird's $78K, the pricing is terrific!
And CCrossfire is right. I have been trying to figure out a way to convince the wife to put a camera in the garage with a screen in the den just to take a look at it any time. It really is that cool a car.
