I've been a customer of Hillmuth since 1992, so I've known them a long time. I had to have some work done on the car, and Billy quoted me for how much it would be beforehand, so I knew what to expect. They fixed the car, and I took it home the same day, but there was a problem with it. He told me to bring it back in the next day so they could check it out. They investigated and found that it was a problem with the aftermarket part they put in. They replaced it with an actual dealer part, and everything was fine after that.
