I agree with doing it yourself, but it's not for everyone. And I would say with electronics available today there is going to be less time spent learning how to fix something mechanical but instead more time spent learning how to configure apps. I am the biggest do it yourselfer there is. When you do one thing yourself, it helps you on the next thing you'll have to do. You will have more tools, more experience, less fear. I would not feel confident in my vehicle's reliability if I did not do the work on it myself. If I hear a little noise, I pretty much know what it is because I know the history of the vehicle. I bought the Grand Prix shown in my little avatar picture thing when it was new. I actually ordered it. I was driving one day and it died. Would not start. I had no idea why. I had to have it towed to the dealer. They replaced the fuel pump resistor. $100 tow charge and $150 for the resistor change. That sucked. The car was pretty new and I was unfamiliar with it. I joined this forum after that and began reading. Now I would know to do the relay bypass thing for the fuel pump to get me home.
