My daughters 2003 Mazda Protege was overheating and needed to be towed to Daniels shop. We got to talking when I got down there and I got worried it could be a blown head gasket. Daniel could see I was worried about it and so he immediately went into action and tested the car to make sure it held pressure in the block. (And let me just say it was after hours.) Daniel was on his way home when I got down there. Daniel and his brother Dallas really do care about their customers and treat them like they would want to be treated if they were the customer. By the Book has been taking care of my families car needs since 2010 when Daniel was a mobile service. I have never been disappointed by the quality care I get from By the Book. - Don D.
