OP here. Only the reflective glass parts get stolen and it takes 10 seconds and a screwdriver. Dealership ones are sold on the black market for half price, though I got the cheap chinese plastic ones and those go missing too. Out of spite I think, since they have my plate number on them and are worth nothing. The police won't do anything, it's a common theft; they told me to get better insurance -_- . Car alarm wouldn't work either, the thief would be gone by the time I arrive. They got stolen 3 times, all nights after I didn't give the guy anything. And the guy is pretty much harassing me now. Like coming to my car to offer to carry my bags or opening my door (creepy, right?). I tried to firmly but politely tell him to leave me alone but nada. Gonna report him for harassment and if he comes near me again he'll get a face full of pepper spray, since that's probably the only way he'll understand. Sorry for the wall of text, and thanks for your supportive/funny comments, they've made my day :D
