Congratulations! It's going to be an exciting 3 mos for you. It has been for us. SO MUCH RESEARCH! And a test drive again.
We looked at price too. Our drops were the leather, dual chargers and the premium sound system. Of these, I will miss the last one, but we tend to talk in the car, so probably won't need it. The leather was a tossup. I'm sure our friends will wonder why this car didn't come standard with leather, but in the hot Arizona weather, I will welcome the fabric seats.
Enjoy this time. You should be well prepared by the time you get the car.
