I started off doing the same thing in my car. Painting the peices blue and then waiting for my body kit and then painting outside blue to match the interior. I ended up screwing myself. It would end up costing me WAY too much in the end for all of that. I decided to stick with my original car color (black) and just had the body kit pieces painted (A LOT cheaper). I am still waiting for Honda to get in the replacement peices in so I can get rid of the ugly blue!
It was a nice idea...at first.
