I don't know about what the other guys said, but I find it pretty fun looking up new stuff to do on my car. I did not know a whole lot about engines when I first started, but I figured I could read instructions and I also am a crew chief on a multi million dollar aircraft, so I know I can turn a wrench. Just do your research get a couple friends, few beers and learn. I would rather do a job on my car than letting some disgruntled billy bob making 6.00 an hour do the job. Now if you never have turned a wrench, cannot read instructions, and prone to screw things up disregard all that I said
