Basically what @
rice_classic said. Everything I've done on my car, I've found a guide for online. I bring my laptop out to the garage, find out what tools I need, line them up and then grab a beer and get to work. I understand the merit behind this, but really, if something goes wrong that I need an in depth repair manual, I'll just take the car to the dealer since it's still under warranty.
Once that warranty goes out when I have a problem, I'll do the troubleshooting, do my research and decide if it's something I want to/can do myself or I'll take it to my mechanic, where parts are at cost and labour is cheap. I don't think he's made any money off my family in years.
