Sounds great if you're into that, but - how long does it take to recoup the investment in the tools? Where do I keep those tools and how much does it cost to store them? Especially things like the diagnostic computer that plugs into my car's computer? How much money/time am I going to invest learning these things? How good of a job would I do compared to an expert? How bad is it going to suck when my engine breaks because "oops, guess I didn't seal something properly" and I chalk it up to experience, and pay thousands of dollars? How much money do I have to blow before I get good at it?

As for little things like changing the oil or the spark plugs - sure, I could do that. But when I take it to an oil change place, they check about 20 different things. And I can change the spark plugs, but I can't check the timing without the equipment.

Let's face it, doing your own car maintenance is for the hobbyist or professional. It takes a lot of time, and isn't my time worth money? And don't I have to pay just as much for parts as anyone else, if not more?

It's like the guy who says "I'll save money by building my own house" and then after a year things start falling apart.... no thanks. Should I do my own dental work, too?

The best way to save money on car maintenance is to get it done regularly, by a professional.
