but if the top is up like on a normal day, the person would have to know where the latch is at the bottom of the seat on the left and climb in and either reach through or around the edge of the seat to get it. that would not be easy.
even if the top is down, a person would have to know where to find the seat latch and be willing to stick around long enough to go through that hassle. how brave are most thieves? most are criminals of opportunity looking for a quick, easy score. (they are lazy or they would have jobs and not steal)
i previously have 17 years in the military and combat experience in the Army Infantry, i have a concealed permit and carry a gun at all times and I am an expert with it. It would be worth someone robbing my vehicle just to catch them doing it.
option a: get shot
option b: get a severe case of pistol whip
option c: lick my tires clean
so my stuff is out of sight, out of mind, the cover is simple and clean, and it allows for more storage than a hide a trunk does while providing small item storage for the rear seat passenger.
