John Schnatter sold the car he loved to keep his father's bar from closing.
He grew up in Jeffersonville, Indiana, where his father was a judge who also co-owned a tavern called Mick's Lounge.
At 16 he was washing dishes and cooking pizzas at a local sub shop, and he spent $1,600 of what he earned on a gold 1971 Camaro Z28, then rebuilt the engine and brakes himself.
He has said the car got him through high school and college.
By 1983 he had a business degree and the family tavern was close to going under, so he sold the Camaro for $2,800 and put the money against his father's debts.
What was left went into $1,600 worth of used restaurant equipment.
Then he knocked out the broom closet at the back of the bar, put an oven inside it, and started selling pizzas to the people already drinking there.
The pizza did $600 its first week, then $1,500, then $3,000, and inside 14 months the business went from bankrupt to clearing over $100,000 a year.
Papa John's went public in 1993 with 232 stores, when Schnatter was 31.
In 2009 he offered a $250,000 reward for anyone who could find the Camaro, somebody did, and he paid it.
