Daniel and his crew are incredible! I have a 97 7.3 diesel that has been somewhat troublesome (parts constantly going out on it, it's an old truck you know?). Every time something goes wrong with my truck, the whole process with By the book is painless and easy. Daniel always finds a way to get my truck in quickly(they've even squeezed me in for a same day appointment a couple of times).They'll constantly call and keep me updated through out the whole process, so I never feel like I'm in the dark. They also do incredibly fast and phenomenal work. You never feel like "just another customer" with By The Book. They treat you like family. Needless to say, I won't trust anyone else to work on my truck. My only complaint is that I can't rate more than 5 stars! - Arthur O.
