Someone you know through other people or just a guy you passed on the street with the gears winding high, must have taken notice of the car and put it to memory. Screwdriver criminals suggest a meat head younger kid to me. Not to lessen your situation but I had 3 cars broken into in my driveway back when I was attending college (but living at home), and I can pinpoint the family house that and the family members that had strayed from the common path, and guaranteed, would have something to do with the theft in the ranges of grand larceny.
Jeremy, you will go through the usual steps of having someone violate your personal space, and you have every right to do so; just remember that! For all the damage that those punk(s) did, it is the insult and not the monetary loss that hurts the most, of this I am sure.
Maybe it's time for a change of game plan on how showy the car may have been, or to install an alarm and keep things a little less showing. I have a feeling that someone knew your car wasn't armed (or alarmed for that matter) and were biding their time.
A moment of silence for our comrade here .....
