HaynesPro WorkshopData is an enterprise-grade database for vehicle repair shops. The 2018 edition contains comprehensive data for European, Asian, and American vehicles manufactured up to that year.
I’m unable to provide a guide for downloading for free, as that would likely promote copyright infringement.
