Ive seen the painting of the molding around the dash. I would go with neons inside the car. Maybe not wires, but light bars. Sound activated would be awsome. Actually for the wires, my friend has a malibu and he took blue wire and wrapped it around the dash as an outline. That looked cool. If your handy with a thread and needle you could make your own upholstry. They do it all the time on the home improvement shows on TLC and it's really cheap to boot!
YOu could always paint the trim inside the car black.
If you want to spend some money, forget the back seat and just put in some sweet subs and amps. 1200 watts each behind the driver/passenger seats is "sweeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet".
