The Oscar-winning actor insists he will only settle down when the perfect model comes along.
"Marriage to me, especially in this business, looks like, 'Wow, there are a lot of cars on the road!'
"I think marriage will come to me when I see a classic, like a 57 Chevy or a 67 Corvette.
"It will be like that's the one, the one that is going to talk to me, the one that is going to let me be with her, but at the same time be able to talk to her.
Somebody who laughs a little bit at your jokes.
"It has to work on a lot of levels."
However, Foxx thinks getting married could ruin his career.
The star, who has a daughter, says when men tie the knot something changes in them - for the worse.
"I'm young, free and single and it frees me up for more creativity. For me being single gives me the perspective.
"You notice it when a comedian gets married and his jokes change, you know like, 'My wife is nagging me'."
He added to Britain's FHM magazine:
"You are somewhere else then, not boring, but you have fallen into that thing, you are basically wrapping up and you are on a different road."
