Police are searching for a 56-year-old Detroit automotive business owner who disappeared during a test drive from his eastside shop Friday.

Racing enthusiast Kenny Moore, 56, was last seen at 10 a.m. Friday outside US1 Transmission, on Gratiot at Jane, according to police and his sister.

"Some men came in for a test drive; they wanted him to check their car out -- and he never came back," said his 56-year-old sister, who did not want her name released in case her brother's disappearance is a case of foul play. "It doesn't look good."

Moore, whose work with cars took him everywhere from Autorama to the race track in Milan, Mich., has owned the transmission shop for more than 20 years. A witness said he seemed to know the men he was with Friday, calling one of them "Marco," his sister said.

She's going to check the Wayne County Medical Examiner's Office today to see if she can find him there.

"He was a well-liked guy," she said, talking about his excitement about car projects. "They’d race cars, build transmissions, get cars ready for shows. It's so overwhelming."

Moore, who is black, is 5-feet 10-inches tall and weighs 230 pounds, with gray hair, thick eyebrows, brown eyes and a scar on his chin. He was last seen wearing a light blue work shirt, blue jeans and black work boots.

Anyone with information is asked to call the Detroit Police Department 6th and 8th Precinct at 313-596-5600.
