The only thing I had to do to my first car was rebuild the carburator and replace the voltage regulator.

My second car was worse. I got if with half the engine in the back seat, two front tires/tyres, no brakes, and an automatic transmission full of water and a busted torque converter. I rebuilt the engine, replaced the brakes, had a mechanic rebuild the transmission, reassembled the whole car, and forgot two important facets of the job. I didn't rebuild the carburator and I don't think I torqued down the bolts to the oil pump. A year and a half later the oil pressure light came on even with a properly filled sump. Later, I ran the engine and the light wouldn't go off. When I checked the oil filter it was dry (the car had been sitting through the winter untouched).

The final indignation of it was having it towed to a dealer as a trade-in on a brand new piece of junk called a Chevy S-10. I think I got ripped off.
