I voted for the "I cast the block myself" one, which is not that far from what I do. I've replaced the clutch in my daily driver in my garage, rebuilt an engine, replaced suspension pieces, a hub/bearing once, alternators, thermostats, fuel filters...you name it I've probably done it. The only thing I don't do is state inspections, mounting tires, and alignments, as those either require state certification or really expensive equipment.
I as well have a Saturn SL2, a 2000. Small world!
And for those of you guys that like DIY cars as well as DIY beer, I give you Grassroots Motorsports Magazine
. The best car mag EVER. Only one magazine would feature a Honda CRX with a Chevy 350 in it on it's cover.
