Well, the money turns out to be counterfeit.
Tye Kuykendall bought an old car from a towing company last year.
He discovered a stash of fake cash in a hidden compartment behind the back seat.
Authorities in Georgia say he bought the car for $400 after it sat for more than three years in an impound yard.
He found the funny money while fixing a gas leak.
Local authorities have called in the U.S. Secret Service to help with the case.
