The driver from Barnsley – who has asked not to be named after being “laughed at by his mates enough already” – says he has no memory of where his white Audi A4 estate could be after leaving it somewhere in the S5 area last Sunday.
Now, he is asking Sheffield to do the neighbourly thing and let him know if they spot it.
The Barnsley man told the Star he left his car last Sunday night (August 15) to go for a evening stroll when he fell over and badly broke his wrist.
He said: “A very kind man in a blue Ford Focus saw I was in pain. He picked me and drove me back to Barnsley where I then went to hospital.
“Only problem is I now have no idea where I left the car.”
He says he has been laid up in hospital since last week and has been unable to go out to search for it.
“It could be in the Shiregreen area, or at least the S5 area,” he said. “I don’t know the area. I was just driving back from a friend’s house and wanted to stop and take a walk.
"I feel like it was near a shop with green shutters and a black gate.”
The Audi’s license plate reads GJ14 ZWY.
