Down Baltimore's Greenmount Avenue, across from a hair braiding salon and a crab shack, the lights for the One Stop Auto Shop flash around the clock, much like shop owner Jerry Greeff's work ethic.
Greeff has been putting in his last days after working with cars for more than 40 years — and he's done quite well. In 2016, his business had $2.5 million in sales.
But he's been working long days for a long time.
"If a customer doesn't have their car, I feel bad for them," Greeff says. "They need their car."
