How are auto body shops categorized? What is the difference between one, two or three types of auto repair shops?

Auto repair shops, automotive hospitals can be divided into a number of levels according to the level of medical care and equipment, there are also specialized hospitals. Of course, the auto repair shop is also divided into one, two or three categories, the specific classification standards according to the Ministry of Transportation (GB/T16739.1-3-1997) Ministry authorized standards. Auto repair shop classification evaluation of the dimensions of personnel conditions, organizational and management conditions, safety production conditions, environmental conditions, facilities, equipment conditions are the main dimensions. Automobile repair businesses*** are categorized into three main groups. Engaged in automotive repair and component repair, but also engaged in automotive repair, minor repair and specialized repair. Class I: Engaged in automobile primary and secondary maintenance and automobile minor repair; automobile maintenance refers to the work carried out to maintain the sound technical condition and working capacity of the automobile; automobile repair refers to the method of replacing or repairing individual components to ensure or restore the working capacity of the automobile for operational maintenance. Class II: Repair and maintenance devoted to automotive specialties, primarily bodywork, painting, cushioning trim, tank, tire, crankshaft repair, and bowling. Category III: dedicated to the repair and maintenance of automotive specialties, mainly bodywork, painting, cushioning decorations, water tanks, tires, crankshaft repair, bowling. Through the above three categories of division, a general understanding of the professional and technical personnel they should have, organizational management and facilities and equipment, scale of operation. Ministry of Transportation in 2004 issued a new (GB/T16739.1-2-2004) Ministry authorized standards, the original standard made some adjustments. The main content is one or two types of enterprise maintenance projects, technicians, facilities and equipment definition gradually fuzzy, the scale of operation and equipment outsourcing have different requirements. Generally speaking, the ability to carry out complete vehicle overhaul and assembly repair should be higher than the level of technology that can only carry out maintenance and specialized repair. For example, provincial hospitals and township hospitals can perform a different range of surgeries. In fact, we can simplify the understanding of the category is mainly 4S stores and some large repair shops, fully equipped, large investment; two categories are mainly based on some of the social repair shops, the general staff of ten to twenty people, with a variety of maintenance operations to repair the general vehicle; three are mainly based on a few fast repair stores, specialized repair stores, such as oil change centers, tire stores and so on. Common automobile repair store requires strength and automobile 4S store compared to a larger investment. For 4S stores, automobile manufacturers have hard requirements to reach a certain scale and need to buy certain equipment. At present, the construction of 4S stores requires an investment of at least twenty to thirty million dollars. Large auto repair stores have to increase their scale and participate in many projects, such as auto parts and components. However, such an investment requires about 200,000 yuan, at least one year before you can see the economic benefits, rather than the money you reserve. Fast repair Lianchen store general investment between 200,000 and 500,000 yuan, occupies a small area, streamlined personnel, parts and repair technology can be unified by the headquarters supply guidance, expensive testing and diagnostic equipment can be **** enjoy. Small auto repair store to buy the necessary tools and equipment is about 30,000 yuan, more car oil, car three core, composed of oil change center. Buy oil can be free to change customers, change the waste oil collection, the end of the month to centralize the sale, the profit is also quite a lot.
