Last time I searched there were no racks available for the 03-06 G sedans. But now I googled and found this:

Any one tried this?

I have seen both the Yakima and Thule on sedans.

is it easy to remove the rack from the car?

I'd assume so. i think they go under the doors or somthing.

The Yakima I had did clip under the door jam area and had locks. It was very easy to remove.
