IS that DAC something you can anchor to the vehicle?

I see a lot of little safes and lock boxes with wire anchors, that frankly, i don't trust much.
Plenty of people have drilled through safe and car to permanently anchor, but i think it would be cool if there was something with studs you left attached to the car, that you could just take it on and off of, with a keyed lock, or releases you have to get to from inside the lock box.
