I think that'll look sick once its done, assuming its done right. And looking at your guys' cars, theres no reason to see why it wouldnt be done right lol. I had a similar idea, but not the skills to do something like that. I need to make something up, because I just have a box sitting in the back of my trunk, with the subs sticking out, amp, and cap. If interested, its at:

I was thinking more of something like painting all my trimmings an alaska b lue inside, and then making a sort of fiberglass encasement. Maybe even taking out the back carpet, fiberglassing, body filling, and painting that alaska blue also. That may be a little much though.
If you guys have any do it yourself jobs, id like to hear em. I havent done much to this bmw yet, Ive only had it for about 3 months. So anything I could do to make it a little more unique, would be good. Even though Ive only seen one other TI in fresno, and it was beat up lol.
