I change my own oil, and do pretty much everything else maintenance and repair-wise on my car. Most quick lube places use questionable oil and even more questionable filters. And I HATE being upselled on everything from wiper blades to air filters. It only takes me 20 minutes to change my oil, and I can usually get a $25 deal on a pureone oil filter and full synthetic at Advance Auto.

The only repair I really draw the line on are timing belts and anything that requires me to hook up a vacuum pump for AC lines or compressors--though I did change out the magnetic clutch and stator on my mom's minivan AC compressor once, but what a pain in the ass that was.

I figure if I can save $500 here, and $300 there on labor and upcharged car parts, I can use that money for cooler stuff--mostly pinball machines.
