i suspect its like an automotive dealership, you can buy all the tools in the world, but without the " factory " training and dealership license agreement you would not be able to do warranty work, regardless of how accurate the work was. as stated kevin will chime in here and set the record straight. as far as special tools go, all mechanical engines, trans and so forth require special tools to some degree, in some cases snap-on or mac, or other quality tool mfg. make tools that are better than factory tools, and alot of mechanics modify or outright make a tool to do a specific job .
