after decade of carry loose jumper cable and separate tool box in the trunk of car or rear compartment of van and suv , I now have everything in one bag . there be enough room for a basic selection of screwdriver , adjustable wrench , flashlight , shop towel , etc. . it be such a attractive package that I have slip a small cable lock through one of the bag 's handle and a tie-down ring in the trunk -lrb- not both handle , as I want to be able to open the bag quickly in a emergency -rrb- . I be concerned that it be so attractive that someone at a car wash or auto shop might be tempt to remove it from the trunk .
