Very nice. Are there lower trim models with the light color interior?
The stock wheels look fine to me. More tires are available in this size and cheaper.
Note that you can adjust your side mirrors to avoid any blind spot:

I do that, but my wife just refuses. She wants to see her own car in the mirrors. For drivers like her, blind spot detection technology is a must.
After the first 1K miles, don't be afraid to rev it up! And use the M mode. By the way, does the owner's manual say anything about transmission fluid change intervals?
