Had a 84' Chrysler LeBaron. Brakes went out on the way home from work. Managed to get it to the closet auto body shop. They had it for three days, charged me $1,200 for a new master cylinder and a bunch of other stuff I didn't know I needed. I paid $500 for the car and tried to tell them to do the absolute minimum to get it going. Apparently that was the minimum.

Drove it home, brakes worked like a dream. Got up next morning, third stop light, brake goes all the way to the floor, I'm drifting into the intersection. I panic, look both ways and gun it through safely. Drove that thing with brakes barely working back to the shop. Calmly told them whatever they did? Didn't work.

Same thing. Another $800 bill, this time the brakes worked for a few more days, then it happened again. I took it to another shop. The mechanic asked what they told me they did and what they charged me for. I showed them both invoices. He pulled me aside with my car still on the lift and whispered to me, "Look man, they didn't do anything. They just filled the brake fluid up. When it all leaked back out is why your brakes kept going out. Imma fix this for a super discounted rate, but you need to get a lawyer, you got lucky not getting into an accident or killed."

I sued the shop, got all my money back and then some. About six months after they settled my suit, I got a call from the local paper asking why I sued them because they were doing a story on the shop scamming hundreds of people out of tens of thousands of dollars.
