A Darwin love triangle dispute may have led a man to park his four-wheel drive on top of his rival's vehicle, and then post a photo on Facebook.

A 29-year-old man, who police say is on his L-plates, was arrested after the photo was posted in an open Facebook forum for high performance car enthusiasts about 10:00am on Monday.

The photo shows a four-wheel drive on top of a sedan in a suburban Darwin street, with a front wheel smashed through the windscreen.

In another photo posted in the comment feed, a man is pictured standing on the tray of the ute and raising his hands defiantly.

The dispute seems to relate to a love triangle between the four-wheel drive owner, the sedan owner and a woman.

Friends and associates of the man posted comments on the forum urging him to calm down and consider his actions, with many others expressing delight and encouragement.

One message in the forum reads "you've just downgraded her in front of the whole of social media ... I thort [sic] you were more mature than this".

Another reads: "[Facebook is] always great for a one sided story ... great job mate jumping the gun and bad mouthing people without solid proof."

Other forum users posted support for the apparent action taken by the man, saying the car's owner got what he deserved.

NT Police have charged the 29-year-old man with criminal damage, driving an unregistered and uninsured motor vehicle, driving without L-plates and driving without a fully licensed passenger in the passenger seat.

He will appear in court on July 8.
