A guy I knew shaved his gas door and had the fill in the left rear wheel well inside the trunk. Doesn't sound like the smartest move! Gas fumes in the car doesn't sound like fun
He shaved a whole bunch of stuff:
Shaved Stuff:
--Door Handles
--Windshield Wash Sprayers
--Roof Lines
--Rear Hatch License Plate Holder
--Emblems
--Antenna Mast
--Gas Door
--Key Holes
--Rear Bumper Lights
