Appearance - Need help with interior designs

I'm gonna go black and yellow for the interior. I was checking out some steering wheels by tekniq autosport with the quick release application and i'm definitely into purchasing one of those.(neighborhood ain't the same no more) After reading a couple of car mags, I see a lot of people have civics that are customized so I gotta be original. I'm gonna go with a Simpsons theme. I'm trying to think up the ways I can work this. So i come here and ask for advice, and maybe someone who has been customizing there car for a while could help me out
