Excellent service, I mean there's nothing better. These people take care of you. They looked over my car when I took it in and I just feel very comfortable with them. The owner at Hye Tech takes good care of me.

He's very courteous. He makes everything simple. I'm not very mechanically inclined, so he explains. He gives you an idea what's going to break, but he does not pressure you. The advance repairs he sees he says you should get this seen. He's kind, when you speak to him its a friendly environment. He's very kind very understanding when you speak to him.
