Cars used to be something just about anyone could repair. I maintain my own cars and have restored a few 1960′s sports cars. The car I drive for most of the year I’ve owned since 1975 (it was already 11 years old). The repair manual for that is one book, about an inch thick. The manual for a recent Jeep is about three inches thick. A 96 Buick Riviera’s manual consists of two, 3 inch thick books. With all the safety and comfort controls in modern cars, mechanics need a degree in computer science.
Your car has a virus, we'll need to take it offline and reboot.
