US researchers have found that driving a flashy car, is a turn-off for both men and women who are looking for a life partner.

美国研究人员发现，寻找终身伴侣的男女会对开豪车的人避而远之。

Despite the hefty price-tag and pleasing aesthetics, both sexes when seeking a long-term relationship are unimpressed by extravagant vehicles, viewing their drivers as less reliable and more sexually promiscuous, according to the research.

In fact, the study suggest that people who are seeking marriage should ditch the sports car and instead choose something sensible.

It follows recent research which found that women believed Porsche Boxster owners were less likely to want a committed relationship than Honda Civic drivers.

"This contrasts with the notion that men's conspicuous resource displays are attractive to women because they reliably signal expected future resource investment in partners and especially in offspring," said study author Dr Jessica Kruger, of the University of Buffalo.

Compared to women, men have a greater tendency to conspicuously display their wealth. But a woman's preference for such displays reflects the type of partnership she is seeking.

For example physical qualities are more important when she has a brief fling in mind, while a man's wealth is more influential when she is deciding on a suitable life partner who can provide for her children.
