Recently, I was out in the garage making forward motion on retrofitting A/C into my Euro-spec 1979 BMW 635CSi. It’s a ridiculous project, but there are reasons for doing it: I want a cold car, I’ve done this kind of retrofit before, I got a good deal on the parts, etc. It also made me think about the larger question of why so many people are into working on their own cars. We might start off doing it purely for economic reasons, but for many of us, wrenching becomes a central, lifelong activity. Why?
