I'm jumping on the "environmentally friendly automotive interior" bandwagon (it's a lonely wagon, but soon, everybody will be doing it!) Yeah, probably not.
Anyway, long story short, I had to rip out the custom stereo and upholstery I had done several years ago because a fuel pump wire shorted out. Stupid me for burying the fuel pump under fiberglass sub enclosures. But since my car was in the shop, I figured I might as well make it an STi, so lots of money later, I have an 03 wagon beast, tuned to run on ethanol, and just happened to have some extra bamboo flooring laying around...
Obviously still a work in progress. The rear seat is gone for good and will be replaced by a carpeted platform (need a place for groceries that won't scratch the bamboo!) and I might build the platform into an amp rack of sorts. The enclosures are almost done, and will hold 2 10" Image Dynamics IDQ subs.
Bring on the: "OMG, just add a disco ball and you could have a midget breakdance party in there!" (FYI, the dome light disco ball is currently out of stock.)
