Small thing that irratates you about your car

What one thing that you know is wrong on your car, that no one else notices, just bugs the snot out of you, if any.
My Dart has a lot of flaws, but the one thing that nobody ever notices that bugs me is the reverse light lenses, they are off of a 66 Dart. The 66s mounted vertically, where the 67s mount horizontally. So on mine the lines are running the wrong way, they mont just fine, but the lines run the wrong way. My orginals were broken and while shopping(ok scrounging a salvage yard)ran across a 66 Dart and picked up the near perfect lenses, maybe not near perfect, but they weren't broke.
