The 42-year-old police officer - dubbed Speedy Cop by his friends - combined an abandoned Cessna aircraft with a Toyota van to make his jaw-dropping ride.
The 27-foot vehicle was originally built for the 24 Hours of LeMons race in South Carolina, US - but since then Jeff has made the car street legal.
Jeff, from Washington DC, USA, said: “You see a plane driving down the street, your first thought is, 'oh my God, a plane crashed'.
"And the second thought is, 'that's the coolest thing I've ever seen'."
Jeff added headlights, taillights and turn signals to make the car safe for the road.
He said: “I kind of am concerned because people focus so hard on this they don't look where they're going.
"I haven't seen an accident yet, but I'm afraid it's inevitable.”
Jeff, a cop for 17 years, has no formal training in engineering or mechanics.
He said: "One of the best reactions was in South Carolina from a group of guys driving Ferraris.
"We pulled in to get gas and their jaws dropped. One of the guys said it was the coolest car he had ever seen - and he drove a Ferrari."
Abandoned for 40 years, the 1956 Cessna 310 was home to an array of wildlife when Jeff bought it for $2,000.
He spent an additional $6,000 transforming it into its present incarnation.
He said: "The floor was rotted away by urine but when I saw it I knew it was perfect."
Jeff hopes to enter the Spirit of LeMons in more races and next plans to drive the plane across the US with his brother.
Jeff said: "I love to compete and build unique vehicles.
"People follow me for miles waiting for me to pull of the road so they can stop and ask what it is.
"It draws attention wherever it goes and it’s really been fun.”
