In any public car park, yes I do. I just think it's better to be safe than sorry, if I left the windows down anyone could just come along and reach in and say steal my phone (even though I always put it in the compartment between the front seats), even though where I live there's probably much less crime than in other parts of the country (especially the big cities). But then I'm just a natural worrier (the media doesn't help and I always see adverts/notices telling you not to leave valuables on display in your car) My mum would always leave the Omega (which is now more-or-less my car) unlocked in the driveway, and I thought it was stupid. As it's nearly summer it's become warmer over here but yesterday as I parked in my driveway I thought about leaving the sunroof open, but then I thought what if one of the birds that sits on the roof of our house flies over and dumps into the car!

By the way I reckon young joyriders (not that I really worry about them) are more likely to steal an older, cheaper car than an expensive one with more sophisticated security systems.
