A commercial car repair manual is written and published by a third party or secondary company and not by the original manufacturer of the car. Whereas a factory service manual is one that is written by the original manufacturers for each of their car’s name and makes. However, commercial repair manuals aren’t made one for each car but rather one commercial repair model is published to fit the needs of several cars with different names and make.
As the publishers of factory service manuals are the original car manufacturing company themselves, they have made sure to include all the nitty-gritty details, related to the respective car, and that too with great precision. On the other hand, commercial car repair manuals are designed in a way that they are bound to give you a generalized view of your car and the maintenance and repair prices. They are not designed to give excessive details as the published assume you know the basic details beforehand. Examples of renowned commercial car repair manuals include iFixit, Haynes, Chilton, Mitchell1, etc. whereas there is a specific factory service manual for each brand of car and for every single one of its models.
Since a commercial manual is published by a third-party source, they’re very easy to find online, both free and paid versions and a paperback version can also be bought conveniently. However, as there is only one publisher of the factory service manual, i.e. the original manufacturing company, finding both, the paperback version and the online version can be difficult. Having said that, even though a commercial manual was published for the general public to use and the factory service manuals were published for the use of workshop owners and professional mechanic, with the right connection and contacts you can conveniently obtain an original and authentic factory service manuals. It is also possible to find credible and authentic factory service manual downloads at allcarmanuals.com from where you can download the factory service manual for free and save a lot of money.
When it comes to commercial car repair manuals, they don’t cover over every aspect of car maintenance and repair but rather mention all the basic and fundamental steps required or issues that could occur in your car. However, factory service manuals include a detailed and elaborate account of all the technical details and steps required in repairing and maintaining your car.
It is very obvious that factory service manuals are far superior and better than commercial manuals in all aspects. However, even though factory service manuals can be relatively more expensive they’re a worthy investment. Having said that you can always look for credible third-party websites and download factory service manuals from there.
