The law enforcement professionals in BC have created a website called BAITCAR.COM...where video cameras, GPS, and stuff are installed into cars and start recording when they're stolen. And...the results are broadcast onto their website. The criminals' faces are blurred, but their voices aren't distorted.
Unless your unlucky like me and you live in a crappy area where values are trending down. Or you can check the real estate records at your local county courthouse and find some "comparable" houses that have sold recently.
