While cars and motorcycles all work in the same way, components do vary between manufacturers. It can be simple to service a vehicle to a certain standard. Where manufacturer branded technician training programs come into their own is where a guarantee may be invalidated by not using trained mechanics. Fine tuning of some top marques also takes in depth understanding of that vehicle and all its individual components to be able to get the best out of it. Most now use complex on-board computers and systems such as timing and fuel injection are controlled centrally in order to achieve ideal performance.
Manufacturer branded training can ensure that students are fully conversant with that vehicle's servicing protocol, parts, and fault diagnosing electronics. It is these domestic high performance (and also imported European and Japanese) vehicles that need careful maintenance. Manufacturers who specialize in luxury or high specification vehicles can often offer manufacturer sponsored training to the right people. It is within their interests to attract and retain the best mechanics in line with their high quality reputation. Some makes are very prestigious, so finding work after manufacturer sponsored training should not be a problem. In fact the Bureau of Labor suggests that employers seek employees with formal training programs in automotive technology as ideal. Figures also produced by the Bureau of Labor, make it clear that pay within automobile dealers is usually better that with general automotive maintenance workshops.
