Make sure that one of the first things you do before you head back to TX is the Cruise Control. You really can't feel the speed in this car, and the fact that it is RED (mine is as well) makes it stand out on the highway - words of experience here.

I had to do several drives from Houston to the Tx/Mx border, and another thing I suggest is definitely taking more than the typical 5-minute stop tp gas up and get another coffee: for one, most likely someone will talk to you about the car, and two, while these cars are comfortable, at least in my own experience, you WILL feel the ride in your lower back.
