My favorite mods on a car are the ones that the general public won't even notice but a true fan of the model will look at and go "Hmmm... wait... that's not normal, is it? How in the hell did you do that? That's COOL!" My second favorite are functional fixes for the little things... slick radar detector or GPS/phone mounts, CB/VHF radios, etc. Things that look OEM but are much smarter than the OEM solutions for the problem.
