Congrats. I know just how you feel - I've got the exact same car, same color, same options, etc. My interior is Jet Black/Dark Titanium, which I really like. I like all the steering wheel mounted controls as well.
For future reference, I discovered that interest rates on financing are negotiable. I had contacted a local credit union and arranged for financing. When it came time to sign the paperwork at the dealership, they asked me if I would do the financing through them if they could match the interest rate the credit union was offering. I said ok, they could try, not thinking they would be able to. However, they came back with an offer 0.1% less than the credit union. Saved me a bunch of time and driving around.
Also, regarding the mileage, I've only filled up once yet and on the first tank I got just under 38 mpg, but I'm not sure how full tank was when I drove it off the lot. My commute is about 30 miles each way, but there's lots of hills.
