According to a research conducted by “extra-marital” dating site IllicitEncounters.com, male BMW owners are the most likely to cheat on their wife. Of the 640,000+ members polled, 19.21 percent of them drove a BMW, which pales in comparison to second place cheaters, who drive Audis (8.79 percent).

It wouldn't be complete without Mercedes-Benz owners, which came in third with (8.23 percent). Jaguar (6.59 percent) and Land Rover (4.94 percent) take fourth and fifth place.

Of course this doesn't scientifically prove that nearly 20 percent of all male BMW owners cheat, it simply means that out of the 640,000 members of the site (which is setup purely to encourage extra-martial affairs), BMWs are the most popular choice amongst men. Unfortunately for BMW, the story is pretty much the same for the ladies, with 11.16% of cheating wives owning BMWs, making it the most popular brand for both sexes.

Thankfully though, if your husband or wife happens to drive a Renault, he or she is only 0.28 percent likely to be cheating. Chrysler and Fiat owners are also very faithful (0.55 percent).

According to the website's spokeswoman, there's a intrinsic link between success and cheating. So the successful risk-takers are significantly represented by their choice of cars. Luxury and German.

To showcase why the results are so skewed, IllicitEncounters.com's main competitor, AshleyMadison.com (which performs the same job of facilitating extra marital affairs), also released data on their members' vehicle ownership a few days ago. The results? You'll be surprised because according to that website, Toyota driver's are the biggest cheaters, with 21% of cheating men driving a Big T, followed by Ford, Chevrolet, Honda and only then BMW.

What do you reckon? One in five BMW and Toyota owners cheat?
