I bought the car on Saturday, after a quick test drive (my brother had driven it and looked at everything previously, and gave it a thumbs up, minus a few scratches and dents) I bought it on the spot and drove it home, despite noticing a huge gash in one of the tires.
I park it in the underground and get all my papers in order, find a place to park my other car, and get ready to do the insurance, papers, new tire, and alarm all in one fell swoop.
Wednesday morning rolls around, I walk outside to go to work, and the car is GONE.
...A week later I get a call from the cops telling me they found the car - it made it 17km before getting a flat tire - yep, the one with the gash in it. The guy tried to fill it up again, gave up, and stole someone else's truck in the area. No damage, not even any lock damage (is this even possible with the use of another key?).
Needless to say, I parked it in the underground again, disabled it, and everything I was supposed to do a week and a half ago ended up getting done on Saturday (yep, valentines day, my girlfriend was very understanding).
Boy do I feel better now.

Oh, then I bought them altezza tail lights I was looking at last year... sigh.
