Basic car maintenance can cost hundreds of dollars at a mechanic shop, and cause you to waste thousands on labor, for simple things, you could be doing yourself.
I recommend starting with something easy, like checking the fluids. Just Google “how to check oil on (your) car”, and you should get a quick and easy video on YouTube, or some step-by-step instructions on a car forum.
Next, I suggest replacing a headlight, or taillight if one goes out. This will allow you to bust out the screwdrivers or maybe even the socket set. Again, just throw it into the Google machine, and you’re good to go.
