[{"role": "system", "content": "A mechanic is a tradesman, craftsman, or technician who uses tools to build or repair machinery. Most mechanics specialize in a particular field, such as auto mechanics, truck mechanic, bicycle mechanics, motorcycle mechanics, boiler mechanics, general mechanics, industrial maintenance mechanics (millwrights), air conditioning and refrigeration mechanics, bus mechanics, aircraft mechanics, diesel mechanics, and tank mechanics in the armed services. Auto mechanics, for example, have many trades within. Some may specialize in the electrical aspects, while others may specialize in the mechanical aspects. Other areas include: brakes and steering, suspension, automatic or standard transmission, engine repairs, or diagnosing customer complaints. An automotive technician, on the other hand, has a wide variety of topics to learn. A mechanic is typically certified by a trade association or regional government power. Mechanics may be separated into two classes based on the type of machines they work on, heavyweight and lightweight. Heavyweight work is on larger machines or heavy equipment, such as tractors and trailers, while lightweight work is on smaller items, such as automotive engines. www.mechanic.com\n"}, {"role": "user", "content": "I have been looking for a good mechanic to do some work on my car. I want to find one who will not make things worse."}, {"role": "assistant", "content": "Yes.  It is a good idea to look for a mechanic who specializes in your particular vehicle.  There are a variety of \"mechanics.\"  But if you should look for one specific to your vehicle.

Some may specialize with the mechanical aspects of the vehicle, while others will deal with the electrical aspects.  There is so much specialization these days."}, {"role": "user", "content": "For good reason as today's vehicles are much more complicated than the days there were like 7 components of a car. The computer systems alone requires extensive training to diagnose."}, {"role": "assistant", "content": "I agree.  Mechanics really should be certified, as they are.  Find a good certified mechanic for your problem or work."}, {"role": "user", "content": "Airline mechanics require extensive training as the systems are extremely complex. And you can't just park the plane on the side of the road if something is messed up."}, {"role": "assistant", "content": "Exactly.  LOL.  Mechanics can be separated into two groups: first is heavyweight; and second is lightweight.  Mechanics for planes would not be properly serviced by \"lightweight\" mechanics.  A jet engine is far different than the combustible engines of motor vehicles.  "}]
