Coat Hanger Uses I've Seen:
Radio Antenna
Attach License Plate
Tie up Exhaust to frame (so it don't drag on the ground)
Replace missing bolts (obviously not for blind holes)
Hose Clamp (Twist tight carefully)
Attach front grill to radiator (major rust issue)
Welding rod
Replace missing/broken Door Latch
Replace missing/broken door, tool or lunch box handle
Get keys out of locked car
Jump start motorcycle or lawn mower (I've done this one - Vehicles touching = ground)
...And that's just off the top of my head ... Welcome to the South...
