Floyd Mayweather is known to drive a hard bargain when negotiating fights, but he could be made to work extra hard for his latest deal.
The world's best pound-for-pound fighter, who typically spends his boxing bounty on lavish possessions, has had offers to buy his Ferrari Enzo if he is willing to meet special requests from buyers.
At a reported $3.8m (£2.4m), the 'Money Man' was never going to sell this car by simply placing it on a garage forecourt, but he may not have banked on any deal hinging on obscure requests for a slice of his time.
Mayweather's personal car dealer, Obi Okeke, said: "I got some crazy request from a 60-year-old man who wants to buy the car but only if he can lace up some gloves and spar in the ring with Floyd in his gym."
Mayweather, known for his "hard work, dedication" mantra, is the highest-paid athlete on the planet and if willing to go the extra mile to sweeten the deal, will turn a profit on the $3.2m he paid for the car in January.
Since then, his array of high-end vehicles mean he has driven the Enzo just 549 miles.
