Years ago when i had my Focus i left the passenger window down, with Sat Nav, bunch of hard to find pc cables and Audigy 2 ZS (fairly pricey at the time) Sound card in the glove box, plus i had about 40 quid in the ashtray bit. Came out in the morning to find the screen inside rather wet and the car colder than usual, thought either i had a massive leak or someone took out my window but i saw no glass, only to push my hand straight through the passenger window
Luckily everything was there still, and i live in Edmonton, the part closer to Tottenham
