Ideas for a baby room

Thinking more about a car/route 66 themed baby room for our little guy. My husband has an old GTO that he restored and after some inspiration from a couple of blogs I spotted here are some thoughts I'm playing around with for Baby E. I really like this bedding. I like the idea of painting the walls a light gray color (probably lighter than what is in this photo). My husband likes the idea of the "racing stripe" on the wall.
If we don't do a racing stripe on the crib wall maybe we will do something like this (imagine the black couch is actually the crib)


Here are some prints I found online that we could purchase and frame. We will probably keep the car theme pics to a minimum so it's not too much. Maybe we will hang a traditional Route 66 tin sign too, and possibly a red toy car somewhere for decoration.
Just a few ideas spinning around in my head.
I like this because I think it will grow with the little guy. It's not too baby themed. I'm not much for "cartoon" looking baby decorations.
