Thieves are allowed on PF as members, watching peoples habits will tell you a lot.
I used to do repo work, involving hiding in peoples back gardens, going through thier bins, chatting to thier neighbours, all this just to make the job eaiser, although every car had a court reposession order, it was not that easy, some were some weren't.
The worst was sitting in a ditch watching a range rover for 14 hours in water up to my waist, very painfull.
Some were watched for days first, if we knew of trouble, and yes repo men do break the law, saying that you can even get into some cars with no damage with just a lighter, ford had some dodgy ones like this.
The point about lock up's etc on industrial estates is that once behind doors of the unit the thief has all the time he wants.
Thieves are not stupid, they know getting caught is only a tiny slap on the hand as well.
