What color is your interior? Mine has the light gray with black dash top and black carpet. The door panels are all gray, including the window switch area, so I plan on spraying part of the door panels black. Make the line from the black part of the dash continue down the door. Then, get some of those brushed aluminum switches, and a Bullitt style shift bezel.
I also want to make an aluminum ring to go around the outside of the gauge cluster...I don't like the ones you can buy that go around the gauge faces. Looks good on S197s but out of place on our cars. You pretty much have to get creative and do custom things like that, because IMO there really isn't much you can BUY that will make these cheap *** interiors look better.
