It's doable... if someone hacks this site they can gain access to the IP address every single user has registered from. From there they can get a closer idea of where you live, then they will know where to look for the car. They may not find it for a while, but they'd know what it looks like. That's why I don't post specifics about what I've done security-wise with any of my vehicles, and you can be sure I've changed more than one thing to stop a would-be thief.
This is not likely, but highly possible
To whoever is reading this and looking up my IP address...I have done nothing to secure my winter ride against theft...it's a blue Pathfinder and it starts up great. I'll leave it full of gas at all times...please enjoy it and don't complain to me about the gas milage
