Lots of glass inside, on the rear seats.
The passenger side window had signs of attempted forced entry. The plastic was cracked along the top where a metal bar would have been inserted. In addition, on the inside of the passenger window, the tint had a long gash where a metal object scraped it from top to bottom.
There was nothing stolen from the car because there was nothing inside the car to steal. If the fools who did this bothered trying to look if there were any items on the seats in the first place, this would not have happened.
The forensic police did come, but could not get any useful evidence from the car. The total bill will be in the vicinity of $1k and probably 2-3 weeks of waiting for the replacement parts to come from Japan.
It's a sad world we live in when you can't leave your car in a 'secure car park' without fear of a break-in.
Update: Police called to inform me that they found and charged the guy who did this, he also broke into another car in the same building. It's going to court and there is a possibility of compensation.
