You can have all the textbook education in the world and find yourself lost when working on late-model vehicles. Late-model vehicles often suffer from weird technical glitches and other weaknesses that require very specific research on each model and the ultimate automotive resources.
We have the expertise to quickly decode wiring diagrams and to carry out a battery of tests to solve any problem without simply replacing parts. You may find other auto repair shops who ask you what your budget is and how much you want to spend with their experimentations.
We never lead our customers on to carry out repairs that they don't need. Pinpointing the problem and recommending something like a new flex pipe instead of an entire exhaust system is the only reasonable approach. It is simply too expensive to guess or to replace unnecessary parts before they rust out, malfunction, or wear.
