Warning: If you click this link there are some swear words in it.
That being said-
Some shops are out there to deceive, plain and simple.
For a guy to take an oil filter off, cut it open, pour metal shavings in it, and then offer a low ball price to purchase the car as "a joke" is anything but a joke.
Thankfully, the shop has cameras, and records their service bays, just like we do. We want to protect your vehicle when we’re not here, and protect ourselves against stuff like this as well.
This is a shop up in Dallas.
Shame on them!
