He didn't think the smell was because of what he found hidden inside: $200,000 in counterfeit bills.
Cherokee Sheriff's Office deputies were called out to his home on Flat Bottom Road on Monday after he discovered the secret stash.
Kuykendall had purchased a car late last year from a towing company. After being towed by an unnamed police agency in Fulton County in 2006, it had been sitting in an impound yard for more than three years.
Upon investigating what he thought was just a gas leak, Kuykendall found a hidden compartment behind the back seat.
Inside the compartment was $200,000, which later was determined to be counterfeit money.
Cherokee Sheriff's Office Public Information Officer Lt. Jay Baker said Thursday that detectives are working with the U.S. Secret Service on the case.
They are attempting to locate the person who possessed the counterfeit money before the car was impounded.
