What did paul jobs do to save money for steve’s college fund?

According to Steve Jobs’ biography, his father purchased old, damaged cars. He then repaired them and sold them for a much higher amount than he had initially paid for them. He saved all that money to pay for Steve Job’s college education. Here is an excerpt from Job’s biography:

“My college fund came from my dad paying $50 for a Ford Falcon or some other beat-up car that didn’t run, working on it for a few weeks, and selling it for $250—and not telling the IRS.”
