Where can I get really cool car magnets?

I have seen these hanging out of the trunk before.

I saw a giant fake band aid someone put over a dent.
How about one that says, “If you can smell my farts, you’re too close, probably”?

Go to this story about Big Mouth Toys They may even custom make them for you.

I’ve always been partial to Woody or Buzz & Woody paired up.

Otherwise, I’ve had good luck with customizing vinyl decals on both eBay & Etsy.

An ex fridge magnet should be cool.

I have seen a trailer hitch cap. It is a deer with a target on its chest. You hook it up to your brake lights through the trailer plug. Every time you are on the brakes the deer flaps its arms and legs up and down. One of the more interesting gags I’ve seen.
