Hey dude. Before you go buying one of those expensive interior trim kits off ebay or wherever, think about painting your interior yourself. In my opinion, I'd take black (or any other color that goes with red) spray paint (make sure you have paint that'll stay on what you're spraying it on in heat or cold!) and paint parts of the interior red. Looks pretty damn good, and you'll save $300 and be proud that you did it yourself

. Check my cardomain page to see how I painted my interior.

Also get cheap (red?) neon at Autozone and put it under the seats or where the legs of the driver and passanger are. Looks cool especially if it pulses to music. I just have a small radio bar, but it's all good.
