Went in for a simple tire rotation and was told my brakes we're really bad and it would cost $170 to get them replaced. Took the car home and got ready to replace the brakes and found the pads we're only half gone. Thankfully I didn't pay the $170 to get new brakes put on. However they did do a very quick job at rotating the tires. < 1 hour
