Maybe money can't buy happiness, but it can bring you love.

That's according to joint research by Discover and Match Media Group. The survey polled 2,000 U.S. adults who either had an active dating platform or met their partner online.

The results: 58 percent of online daters say a good credit score in a potential partner is more attractive than driving a nice car. Fifty percent say good credit is more important than an impressive job title. And 40 percent said they favor good credit over physical fitness.

That's because credit "scores don't lie," says Kate Manfred, vice president of brand communications and insights at Discover.

"They tell the truth about who you are as a person and how responsible you are, which is incredibly correlated with how much of a good companion you'll be in life," she says.

"We know credit score is an important measure of financial responsibility, and we had a core hypothesis … that it would translate into the dating realm. It turns out it did."
