Modern Cars are Technological Marvels. In the last 100 years cars have changed a lot. Today's cars though they may not look much different, are much more complicated than cars produced just a few years ago. Electronic and computer controlled transmissions, engines, and everything in between have many sensors and are run by complicated computer systems. All of this sophisticated technology has made do it yourself car repair harder than ever and near impossible without the proper tools and computer diagnostic scanners.

As a customer, you should look for a repair shop before you need it. If it's too late for that, try to get more than one opinion. Many times cars have been referred to us that only need a sensor replaced or something as simple as a new battery instead of a transmission rebuild. This is why the honesty and knowledge of who is fixing your car is so important. You're forced to rely on what the repair shop tells you. It is a myth that everyone in auto repair is a theif. Many times an auto repair shop is telling you what they honestly believe. The only problem is that they don't have the knowledge or skills to make the correct diagnosis. In the end, you won't know and honestly, it doesn't matter. So the moral of the story is to make sure the shop you deal with knows what they are doing. You can do this by checking for affiliations and certifications like ATRA, ASE, and others.
