sorry i dont have the make and model but i picked up a small travel safe a couple years ago, and it attaches around a pole etc. You unlock it to access the inside, and thats how you undo the cable to free it. Ive used it in the car before, i dont know how strong it would be because ive not tried to gorilla open it, but if you attached up under a seat it would be really hard to get enough leverage to pull it free i think
