what i did is just the begining and it was only s test i have all my original interior parts still all the painted parts were taken out of a 96 gxe parts car i have in my yard... so i can always go back to stock!!!!!
I think that if you really wanted to make a sweet interior, have some CF made to fit those pieces and go with a black-and-white color scheme. Get a CF hood, black-housing projectors, Mike's Skyline grille in CF, and stick with dark-colored wheels. I think that would look incredible.
i personally like it man. the only thing i could question is the wood grain trim. it looks good...but im a fan of keeping a theme. such as having the pieces you painted red in wood grain, or having the parts that are wood grain be red. just a suggestion..i like it as is too
