While not very show but did you think of tan or a light tan interoir?I hate tan interoir in a real car but it goes really good with that color blue.
That or Black and blue wouldnt be to bad.Maybe red carpet, front seats (from a Lancer model) black leather back seats,dashboard etc...
Dont go Yellow and black sounds nasty, but heck it might suprise me.
Good luck.
Could you nbuild another and send it to me?I wont use it

Ill build my own from it.
Email me.
Thanks
