I would go buy a Haynes Repair Manual for the car you have now and read through it and maybe start doing your own repairs. You will find out things about your car and its parts that you never knew before.
Since we were kids, my Dad did a good job making sure that my brother and I knew about our vehicles and how they work and how to repair them. So I rarely take my vehicles in to get them repaired now, I do it myself or with my brother.
