I know it's not sexy, but what about replacement backcaps for the foglights, with instead of the pass-threw, a whole for a grommet, so when you install HID fogs, you can get your wires out.
Hey, i just stumbled on this page. It's awesome.
I had an idea. How about an insert that replaces the ash tray with an arm that can hold a phone?
it would be really nice if you could take it out, so when you are not using it the door still closed.
