Mechanics see it all.
A quick search of the "Just Rolled into the Shop" sub-reddit will reveal the challenges that mechanics deal with on a daily basis -- cars they're excited to work on and grotesque examples of neglecting service or repairs -- but I see it as a kind of people-watching. After all, our cars are very much an extension of who we are, the type of life we live, our interests, and our sense of humor, where we've been, where we're going, etc. Even if you hop into the most bland champagne-colored Corolla, something will trigger your imagination -- whether it's their taste in music, a layer of pet hair that's as thick as fiberglass insulation, or (as one story I heard) a loaded snub-nosed 357 magnum casually resting on the passenger's seat. That's why we want to bring you a few automotive repairs that you should obviously never do but that prove that your mechanic's stories may contain less fiction than you think!
I hope this is a joke.
Helps with bugs?

When they said exhaust hanger ...
Is a car you're willing to do this to worth locking?

Zip-tie roulette.
Keep two hands on the ... vise grip?

Need we say it again? While your buddy may be MacGuyver, stuff like this is never a good idea. Do you know of anyone who has a ridiculously repaired vehicle? We want to know about it! Let us know, or tell us your story in the comments below!
