I've taken to repairing just about everything myself. Usually it's pretty easy and you can find instructions and parts via Google for just about anything. I'm repairing the washer tomorrow. Parts were only $30. The repairman quoted $300.
Several years ago the water pump on my wifes car was leaking. It was just a bad/old gasket. I got this! A couple of bucks for a new gasket...easy peasy. Replaced it, but I was careless tightening the last bolt...put it in crooked...snapped it in half. Dammit.
So now I had to spend over $25 on a screw extractor set and titanium drill bits. Drilled the hole, inserted the extractor, tried to remove it...
Went back to home depot, bought a couple of c-clamps, and called it good. Eff it. No more leaking.
Was supposed to be a 2 dollar repair, and my thumbs increased it by almost 20x that amount.
My wife won't let me near her car anymore.
We ended up selling it several months later. It was still leak-free. Just needed to remember to periodically check that the engine vibrations didn't loosen the clamps.
